At a lower atmospheric pressure, there's less force pushing down on the surface of the liquid meaning the energy threshold to jump from liquid to gas is lower. Since it requires less energy to become a vapour it can boil at a lower temperature -- or room temperature (temperature is simply the average kinetic energy of atoms in a substance)
Not accurate, have you wondered though why you can't cook (boil) an egg in this water? Bubbles forming when you boil water to cook ...pasta and bubbles forming in this experiment are one and the same: Gas molecules forming and escaping from the water. The difference is the method used. One is the introduction of energy (heat) and the other is reducing the atmospheric pressure around the water. Think why it is recommended to add salt in the pot for cooking: Because it helps the water reach the recommended higher energy point (e.g. at least or a bit higher than 100C) and faster. Bottom line is you cannot boil (cook) hard boiled eggs in this kind of vacuum environment. so you guys should stop saying, boiling. It is not!
@@XwpisONOMA Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. Wikipedia It's literally boiling.
@@XwpisONOMA Cooking an egg is caused by the denaturation of proteins inside the egg. All proteins denature at a high enough heat. As the proteins denature, they permanently change shape, although an egg has been "un-boiled" in a Nobel Prize winning experiment in 2015. Boiling water is fundamentally different to boiling an egg. Boiling water changes the state of the water, and boiling an egg denatures the proteins inside the egg. Hope this helps :)
I was studying physical equilibrium in chemistry and I was reading about what is boiling point(Temperature at which vapor pressure of liquid become equal to external pressure). Then I thought that if the external pressure is reduced then the boiling point will also be reduced and then I searched on UA-cam what will happens when we boil water in vaccum and then this masterpiece video came to me. Thank you very much bro. You always give me practical knowledge of physics and chemistry.
@@noahway13 It gives the water enough energy to overcome the pressure of the air. Allowing it to basically jump out of it's liquid state. It's the difference between jumping on the moon and earth. You can get better results in once place with less effort, but you can still achieve the same effect with more energy if you really wanted to.
If I'm not mistaken, the freezing point of water is also determined by pressure. It probably doesn't have to do with residual warmth from the vacuum chamber, since the water itself was at -0.1c.
1:22 Your explanation for boiling isn't 'wrong' per-se, but it's incomplete. What you describe fits the definition of 'evaporation' better than boiling. Boiling is when the vapor pressure of the liquid (which changes with temperature) exceeds the pressure exerted on the liquid by the surrounding atmosphere. This helps to explain why reducing pressure can induce boiling without changing the temperature (reduction in external pressure-no change in internal vapor pressure). It also explains why raising the temperature, as is more traditionally done, causes boiling (no change in external pressure, but a rise in internal 'vapor pressure' of the liquid).
Do you know if the bubbles in the water (the air dissolved in the water) are also just pure nitrogen molecules? Or do the nitrogen and oxygen molecules always stay close to eachother to form air (the bubbles)). Hope I'm clear ineough :)
@@Scrungge Hi Berton. I'm not clear on if you are asking a question related to my post? The 'air bubbles' in boiling water are actually water vapor gas bubbles, not 'air' at all. No nitrogen involved either. Perhaps I'm not clear on what you are asking. EDIT: I just re-watched the video because it has been some time. I see you are probably referring to the bubbles he mentions at 2:15. The answer to your question about whether those air bubbles are truly mixed air with the same gas composition or are pure nitrogen or oxygen, etc. I do not know.
A video showing whether or not a fruit or a vegetable ages in vacuum would be cool. that is if they don't burst already, so a simple video with fruits in a vacuum chamber should do the trick
Great stuff, would have been nice to have a little device to drop an ice seed into the 0c water to see how the vacuum cooled water would react, would there be enough nucleation from impurities considering the air was pulled out of it?
Why is the surrounding glass is cooler? When water heats up and boils, it takes in energy to overcome intermolecular forces of attraction between each H2O molecule, thus turning into a gaseous state. This is also called an endothermic reaction. (Takes in energy) In this case, since there is no constant supply of heat energy supplied, they will absorb energy from its surroundings to break the bonds, causing the surrounding glass panels to cool. (Internal temperature of water should remain the same) yay finally something I learnt from school is used to mke me seem smart even though Im not xp
i see.. so this just added to my understanding of what happens on air separation system of oxygen, argon and nitrogen. although it doesn't technically like the vacuum chamber, like the opposite way since it compressed the air to higher pressure and not suck it out, the boiling part was the same to the way it form just the fog then the watery fog it produce was the high purity liquid oxygen. Imagine at negative degree it says boiling point? So its not about the heat, but the state it starts to evaporate.. thank you for this experiment and it enlighthen me on the field of work I was on.

So would the water keep boiling off at a certain pressure, or would it stop boiling once it cools to a certain point? Also would you have to keep the vaccuum running because the boiling water turns to gas and that gas repressurizes the chamber? Thanks 😃
its sick!!!! ya pressure will speedy back to normal and at normal pressure water will freeze will be resublimation, from gas to ice instantly but it will be like implosion. it will suck some air and idk what will do but its dangerous
DANG JOS it will freeze because its below 0°C it just doesnt freeze while in the vacuum chamber because changing the pressure decreases the point at which it does so (just like it decreases the temperature needed to boil)
+Lars L Lowering the pressure over water actually increases its melting temperature; it doesn't decrease it. I would question the accuracy of his thermometer. Even if the thermometer is accurate, the most likely reason for the lack of freezing is super cooling. Not a reduction of pressure. The triple point of water is actually at 0.01 C
looking at the triple point graph of water, increase in melting temperature while lowering pressure only happens at 212.9 MPa until 10MPa, the rest of the pressure is opposite of what you said. Triple point only means at that pressure all 3 states of that matter can exist together. I would not question that thermometer, it is only a matter of time that the water turns into solid/gas because the pressure definately are below the triple point of water due the the temerature kept decrease in the water, at one point the temperature surely will stop and that will be when the freezing happens. @DANG JOS you should take a good look at the graph seriously...
check it. pressure are at left temperature at down. liquid nitrogen will make gas. get random point at nitrogen when he is liquid and go down to see what will be when you lower pressure. it will be gas like water but if nitrogen would be solid it will do nothing.

Kulvis Flabu when we use compressed can (paint/ butane) the contents are actually decompressing, isn’t it? So I think the cooling effect can be attributed more to the movement of the propellant’s molecule rather than the boiling of actual liquid content. Same concept with refrigerants in aircons and refs. Or are these all the same principles?
I think it didn't freeze because -as it is tap water- it has different things desolved in it like salt, Magnesium, etc and with the ions in it, the freezing point of it decreased, thus never freezing while boiling. Long ago, Cody from Cody's Lab did the same thing, but I believe he used destilled water and managed to freeze it.
One question in the end, when temperature of water reached freezing at normal pressure. Would the water freeze instantly if you would open vacuum chamber or would the temperature of water rise?
Neither. The temperature decreases because it boils. That means that for it to increase it would have to undergo the reverse process. When you open the chamber it does, and it condensates, but on the walls, no contact with the water, so the heat doesn't go back in. Plus, most of the vapour which extracted the heat in the first place was taken out by the pump as it tried to maintain a vacuum. Freezing also needs a nucleus. So unless you tap on the glass, it wouldn't freeze in normal pressure either at sub zero temperatures.
Hey Action Lab, is it possible we could see what a fire would look like in the Vacuum chamber if you used an oxidizer as a fuel source? That would be pretty cool :D
Cody's Lab YT channel did that. The result was that nothing sustained burning including gunpowder, rocket fuel, and perchlorate explosives. It would smolder in the laser but not actually ignite.
+The Action Lab To add to the definition of boiling, it is when the vapor pressure of the liquid equals the atmospheric pressure. As I learned from a physics professor once, the internal pressure of a steam bubble is equal to the vapor pressure, and if that is smaller than the outside pressure, then the bubble will literally collapse back into the liquid. This is why, when you put water on a hot stove, you see water on the bottom get hot enough to form a bubble, but it collapses before reaching the top. This is of course because the water isn't yet hot enough to sustain the steam bubbles
Sir I think it did not froze because as Boiling Point differ at certain Pressure same will happen to the Freezing Point it will increase also instead of 0 to maybe negative something depending on ambient pressure.
this is earth, a vacuum on the surface of earth is still affected by earth's gravity,so it should be no difference.And they also need a larger vacuum chamber for that :P Things are different at space station or satellite is because they are not stationary, they move alot (have momentum) to counteract the gravitational pull so that they wont fall down to earth. Point is Vacuum simply state that that space has no gas in it
Since the majority of mass of the vacuum chamber is the solid walls of the container, removing the air from inside will not noticeably change its weight. This is why vacuum airships that could exist in concept, have never become a reality. It is impractical to build a lighter-than-air vessel with walls rigid enough to support the vacuum inside the vessel.
If we could create a breathing apparatus that used a vacuum to take air out of the water potentially we create oxygen tank-free scuba gear. That would be cool.
+Daniel Padgett that's a cool thought! So a small vacuum pump connected to a tube that continually brings in new liquid that has the pressure lowered until the dissolved air is released. That air is then returned to normal pressure. It wouldn't be much volume of air per volume of liquid though, so I don't know how plausible it would be, but that would be cool.
Of course, development could create a strong compact vacuum that would increase water flow and air supply to a faster rate. All ideas can be improved upon. Love your videos they're great and very informative.
The Action Lab way late to the game on this, but "normal" pressure in this case wouldn't be the same as on land. Keep in mind, you're under water, so you're under a lot of pressure. The air you breathe would have to be pressurized, too. If you went to the bottom of a swimming pool with a rigid tube, and tried to breathe through it, you'll discover your diaphragm isn't strong enough to match the pressure at much of any depth. PLEASE don't try this, as there are inherit dangers involved. I'm a diver, both recreational and (retired) commercial. As such, I'm studied in things like gas laws, and basic human anatomy (at least in so much as what parts of the body are most affected by pressure changes. Don't use yourself as a human guinea pig trying to test gas law. I don't want to appear in court when you pop your lungs, shatter teeth, blow out your ear drums, etc.
use electricity to hydrolysis for pure oxygen supply under water and it done according to internal combustion system as we need water intake in it's pure forms so we need filter and a efficient battery will provide power to this setup and underwater we living our lives forever without the need of atmospheric oxygen battery are charge with waves energy or solar energy
It seems kind of convenient that the dissolved gas just happens to escape at around the same temperature and pressure that the water vaporizes. I think a better demonstration would be helpful - preferably with a substance that both contains dissolved air and boils at a much lower pressure so that there's a clear demarcation point at which all the trapped air has been released and yet the substance has not yet begun to boil.
When water boils does the atmospheric pressure become higher? Also do you have to continue vacuuming in order for the pressure to remain constant? Or can you vacuum a chamber and let it sit at that atmospheric pressure then warm up the chamber to warm up the water and let it boil at a low temperature?
the pressure will increase just enough to stop the boiling effect, yes you have to keep pulling vacuum. the water will turn to ice with a good vacuum pump. you can also heat up a bottle of water to boiling point then take it off the flames put a cork stopper. the water will stop boiling after a short time but by placing your hand on the bottle it will start to boil again. this is because you remove heat from the trapped air and it creates a vacuum in the bottle and the water boils.
An interesting side note is that those air bubbles coming out of dissolution as the pressure is decreased is exactly what happens to a diver who gets "the bends" or decompression sickness as they ascend from depth too rapidly. The nitrogen that has dissolved in their blood and tissues comes out of dissolution rapidly, forming bubbles that cause joint pain, embolisms, even death, as the pressure is decreased. The way to combat this, other than mixed gas diving, is to decompress at a prescribed rate, which allows the nitrogen to be removed slowly and gently through exhalation instead of forming bloodflow-impeding bubbles.

I heard years ago from an army buddy that up in the mountains the tea tastes foul because the water doesn't boil hot enough. Not sure how that makes a difference not being a tea drinker myself
@@noahway13 yea watched the whole thing. Found it interesting. Had a relevant question, can you answer it? Or do you want to be more of a condescending tool about it?
I believe you could cook with it. As it really depends on temperature vs the actual boiling of the water (think of a microwave and how it heats up the actual water molecules themselves, no boiling required.)
Action Lab...good stuff! I don't know if you've done this before, but what would cooked noodles do in the vacuum chamber do? Ravioli, rigatoni, or egg, or any other type of noodles. Would they swell up, or shrink, or remain the same? I know what my guess would be.
That's not what sublimation means. Sublimation means that something goes from the solid phase to the gas phase without ever being in the solid phase that usually is in between.
+Neil Baxter because the definition of boiling is when the vapor pressure of the liquid is greater than the pressure surrounding the liquid. Bubbling is when there are simply bubbles of a gas in a liquid. Boiling and bubbling are completely different phenomenon.
Oxygen liquifies at 750PSI. If further pressure is applied the volume will not change but what about the temperature ? If for example 5800PSI, would the cylinder warm up or stay the same?
Here is something interesting. On mars (6 millibars) makes water ice does what dry ice does here. It sublimates. Can you show that on a video sometime in the future?
Yes, but it is a lot less sensitive to pressure than the boiling temperature. Look up the phase diagram for water, on a pressure vs temperature plot. The solid-liquid line is a lot closer to vertical, than the liquid-vapor curve. Water is a special case where the solid-liquid line has a negative slope, because ice expands when freezing from water. Very few other substances do this. Most substances would have a phase diagram, where the solid-liquid line has a positive slope, like the phase diagram of carbon dioxide.
At the end of the video I think it did not freeze since the pressure was very low => According to water P-T graph, the temperature has to be much smaller than 0ºC in order to change to solid
I was wondering if you'd share some information about your vacuum chamber and pump setup. I am interesting in duplicated but got little idea of specifications?
Why does water take so long to transition from liquid to gas in a mear perfect vacuum? If you shut the vac pump off, will the liquid continue to transition to gas until it builds enough pressure to stop for a given temp; or will it simply never convert.
Just so you know, pure water does not freeze until -70c at -1bar of vacuum. So in space you could have water that is -69c as a liquid, if you warmed it up from absolute zero that is.
Hopefully, this gets answered. While the water boils at a lower temperature because of the lack of pressure, does it lose its cooking abilities? let's say, can you make coffee with water boiling at 32°? does the same effect affect the coffee itself also?
Yea of course, what cooks food is the amount of heat (energy) added to the water to bring it to boiling, this is what affects the food molecules, and not the physical process of boiling itself. This is why you can also grill and fry food without boiling water.
You can’t freeze the water this way. Because at lower pressure the freezing point is also lowered. It’s not zero degree anymore... Similarly, you can freeze non cold water at a high pressure.
It would sublime without producing the fog you usually see. The fog you see when dry ice sublimes, is water condensing out of the surrounding air. The CO2 gas that sublimes from dry ice is invisible.
No. The fact that the water is boiling actually hinders you from using water from cooking, rather than helping you. You want the water to be in a liquid state at as hot of a temperature as possible, in order for it to be effective at cooking food. This is the working principle behind a pressure cooker, so you can get the water to be liquid at a much hotter temperature. This is also why products cooked in boiling water have high altitude instructions, that require a longer cooking time.
If you put ice in a vacuum chamber would it melt under vacuum and refreeze once pressure returns? May have to do this in a walk in freezer so the temperature stays freezing?
Yes, it will just take more energy to heat the water to its boiling point at said pressure. For example, at 10 bar, approximately 10 times atmospheric pressure, the boiling point of water is 180c.
This is as the same thing when you go to a highier place like a mountain water boils much faster, if you go even highier you will require less energy(heat) to boil the water
so it is possible to drown a fish
Mind blown
Wow.
Dont change the aquarium water or airate it.. and the fish will drown..
Yes fishkeepers know this, when oxygen is low in water fish drown the first sign of low oxygen is fish going to the top of their water to breathe.
Is it possible to fly on air without wings?

No i watch that channel he sounds different than this guy
Cool! Next time my city puts a boil water notice I'm going to put my tap water under vacuum pressure to do it B)
Do a test how much the vacuum chamber weight when in vacuum!
this is earth, a vacuum on the surface of earth is still affected by earth's gravity,so it should be no difference.And they also need a larger vacuum chamber for that :P
Things are different at space station or satellite is because they are not stationary, they move alot (have momentum) to counteract the gravitational pull so that they wont fall down to earth.
Point is Vacuum simply state that that space has no gas in it
Lol gravity
Since the majority of mass of the vacuum chamber is the solid walls of the container, removing the air from inside will not noticeably change its weight. This is why vacuum airships that could exist in concept, have never become a reality. It is impractical to build a lighter-than-air vessel with walls rigid enough to support the vacuum inside the vessel.
This is one smart dude. Thank you so much for this AWESOME explanation of WHY my chamber vac liquids boil
If we could create a breathing apparatus that used a vacuum to take air out of the water potentially we create oxygen tank-free scuba gear. That would be cool.
+Daniel Padgett that's a cool thought! So a small vacuum pump connected to a tube that continually brings in new liquid that has the pressure lowered until the dissolved air is released. That air is then returned to normal pressure. It wouldn't be much volume of air per volume of liquid though, so I don't know how plausible it would be, but that would be cool.
Of course, development could create a strong compact vacuum that would increase water flow and air supply to a faster rate. All ideas can be improved upon. Love your videos they're great and very informative.
The Action Lab way late to the game on this, but "normal" pressure in this case wouldn't be the same as on land. Keep in mind, you're under water, so you're under a lot of pressure. The air you breathe would have to be pressurized, too.
If you went to the bottom of a swimming pool with a rigid tube, and tried to breathe through it, you'll discover your diaphragm isn't strong enough to match the pressure at much of any depth. PLEASE don't try this, as there are inherit dangers involved.
I'm a diver, both recreational and (retired) commercial. As such, I'm studied in things like gas laws, and basic human anatomy (at least in so much as what parts of the body are most affected by pressure changes.
Don't use yourself as a human guinea pig trying to test gas law. I don't want to appear in court when you pop your lungs, shatter teeth, blow out your ear drums, etc.
use electricity to hydrolysis for pure oxygen supply under water and it done according to internal combustion system as we need water intake in it's pure forms so we need filter and a efficient battery will provide power to this setup and underwater we living our lives forever without the need of atmospheric oxygen
battery are charge with waves energy or solar energy
according to indian literature it's already done by nivat kavacha rakshasa in india in ancient times of vedic kaal
I would love to see you then carbonate the water that has had all the dissolved gases removed. Would it be super carbonated?
I learned a lot, thanks so much man
put ballistic gel in the chamber!
RainchenYT Rain it wouldn't do much
it wont?
RainchenYT Rain It's just going to melt.
It wouldn't even do that.
Will it cool the temperature inside????
what happens to liquid nitrogen in vacuum chamber
MOURYA SHAH most likely it'll boil faster and turn back into gas.
MOURYA SHAH it loses more energy, until the point it freezes and turn into solid, he already made that
MOURYA SHAH it would rapidly freeze.
It seems kind of convenient that the dissolved gas just happens to escape at around the same temperature and pressure that the water vaporizes. I think a better demonstration would be helpful - preferably with a substance that both contains dissolved air and boils at a much lower pressure so that there's a clear demarcation point at which all the trapped air has been released and yet the substance has not yet begun to boil.
Carbonated water probably would be a good choice for that demonstration.
U r showing all in practicall...nice
Last time I was this early
my parents loved me...
just kidding, my parents are dead.
Levitating Gaming 😞
:(
OreeXII thats not funny 😡
Levitating Gaming good
G Savvy he is not even laughing
What a good toast at the begining. Cheers
wow, so interesting! l loved it!
Very informative, thank u.
When water boils does the atmospheric pressure become higher? Also do you have to continue vacuuming in order for the pressure to remain constant? Or can you vacuum a chamber and let it sit at that atmospheric pressure then warm up the chamber to warm up the water and let it boil at a low temperature?
the pressure will increase just enough to stop the boiling effect, yes you have to keep pulling vacuum. the water will turn to ice with a good vacuum pump. you can also heat up a bottle of water to boiling point then take it off the flames put a cork stopper. the water will stop boiling after a short time but by placing your hand on the bottle it will start to boil again. this is because you remove heat from the trapped air and it creates a vacuum in the bottle and the water boils.
This is next level procrastination for me. I have so much work I should be doing. How did I get here
An interesting side note is that those air bubbles coming out of dissolution as the pressure is decreased is exactly what happens to a diver who gets "the bends" or decompression sickness as they ascend from depth too rapidly. The nitrogen that has dissolved in their blood and tissues comes out of dissolution rapidly, forming bubbles that cause joint pain, embolisms, even death, as the pressure is decreased. The way to combat this, other than mixed gas diving, is to decompress at a prescribed rate, which allows the nitrogen to be removed slowly and gently through exhalation instead of forming bloodflow-impeding bubbles.
So space is full of boiled water or ice
Amazing video’ thank you. You had great teachers.
Can you do a ''Does condensation can happen inside of a vacuum chamber''?
Can you cook mac' cheese in it?
if you like to eat mac and cheese that isnt cooked at all then yes
Karan Randhawa spoiler... it is boiling technically, so i was just wondering
So would our body tissue/blood boil or freeze if we stepped out into the vacuum of space without a suit?
Simple answer: yes.
I always thought fish breathed water☹️
MIND then he just learned something new so stfu
MIND you're
Irony overdose
Random User Not everyone learned that in biology ya know.
The information its really cryptic as they just say gill and shit
or he just is a younger person
heck he could be 10 or 8 although he may not know that he may know something you don't
so SHUT THE FUCK UP AND STOP USING DISEASE AS YOUR MEANS OF INSULT
you know I have.... ahh shit people won't read till this bit if you did
fuck u . LONER
or your a nerd
Chill Charmander oh...
Your canserious , Thats' alzheimer.
Can you cook in that? Like could you boil a potato? Or is that just for heat? Is this how a pressure cooker works?
I heard years ago from an army buddy that up in the mountains the tea tastes foul because the water doesn't boil hot enough. Not sure how that makes a difference not being a tea drinker myself
Did you listen to the video at all?
@@noahway13 yea watched the whole thing. Found it interesting. Had a relevant question, can you answer it? Or do you want to be more of a condescending tool about it?
@@killahtomato89 I'm over my condescending tool moment. Thanks for calling me on it. What is your question?
I believe you could cook with it. As it really depends on temperature vs the actual boiling of the water (think of a microwave and how it heats up the actual water molecules themselves, no boiling required.)
Action Lab...good stuff!
I don't know if you've done this before, but what would cooked noodles do in the vacuum chamber do?
Ravioli, rigatoni, or egg, or any other type of noodles. Would they swell up, or shrink, or remain the same?
I know what my guess would be.
My guess is that they would dry out to their original rigid form.
do a face reveal
Bunker Binkleton he already did it
heck, this comment totally wasn't sarcastic
srpska zabava Yes, I didn't see the first reply
Bunker Binkleton 8:20
DaffyTV I know, yes. Why doesn't anyone get the joke?
When the gases boil of from the water is there a way to collect the oxygen
It's called, "sublimation," which means it becomes gas but temperature always remains the same.
That's not what sublimation means. Sublimation means that something goes from the solid phase to the gas phase without ever being in the solid phase that usually is in between.
So pressure diffrence also changes waters freezing point.
Yep. That's how pressure cookers work.
why say "boiling"? it doesnt heat up! should be called "bubbling"
+Neil Baxter because the definition of boiling is when the vapor pressure of the liquid is greater than the pressure surrounding the liquid. Bubbling is when there are simply bubbles of a gas in a liquid. Boiling and bubbling are completely different phenomenon.
Water in a vacuum first bubbles then boils!
Felix Rojas That's because some parts starts boiling first
So little bubbles aren't boiling but big bubbles are?
We only assosiate it with heat becuz MAC N CHEESE
Please may I request you to try this experiment on candle wax. To see if reduction of pressure can cause wax to melt at room temperature.
Thank you for explaining everything!
It was really helpful!
Oxygen liquifies at 750PSI. If further pressure is applied the volume will not change but what about the temperature ? If for example 5800PSI, would the cylinder warm up or stay the same?
Here is something interesting. On mars (6 millibars) makes water ice does what dry ice does here. It sublimates. Can you show that on a video sometime in the future?
Somebody: WILL IT BOIL WILL IT TURN TO VAPOR?!
Me: WILL YOU SHUT UP WILL YOU STOP
When you open the valve and release the vacuum by adding air, does that air dissolve back into the water?
Does the freezing temperature also change regarding the pressure?
Yes, but it is a lot less sensitive to pressure than the boiling temperature. Look up the phase diagram for water, on a pressure vs temperature plot. The solid-liquid line is a lot closer to vertical, than the liquid-vapor curve.
Water is a special case where the solid-liquid line has a negative slope, because ice expands when freezing from water. Very few other substances do this. Most substances would have a phase diagram, where the solid-liquid line has a positive slope, like the phase diagram of carbon dioxide.
At the end of the video I think it did not freeze since the pressure was very low => According to water P-T graph, the temperature has to be much smaller than 0ºC in order to change to solid
Have to cover this in my next upload!! Great action!!
I was wondering if you'd share some information about your vacuum chamber and pump setup. I am interesting in duplicated but got little idea of specifications?
Science is beautiful
Gas particle move faster than liquid particle, so should the tampture go up once all the water boil up?
Why does water take so long to transition from liquid to gas in a mear perfect vacuum? If you shut the vac pump off, will the liquid continue to transition to gas until it builds enough pressure to stop for a given temp; or will it simply never convert.
Can you please list the equipment you used to recreate the experiment in a classroom for children?
Just so you know, pure water does not freeze until -70c at -1bar of vacuum. So in space you could have water that is -69c as a liquid, if you warmed it up from absolute zero that is.
You didn't show the thermometer at 5:28, what was the temperature at that point?
Excellent superb 💧🌱
Hopefully, this gets answered. While the water boils at a lower temperature because of the lack of pressure, does it lose its cooking abilities? let's say, can you make coffee with water boiling at 32°? does the same effect affect the coffee itself also?
Yea of course, what cooks food is the amount of heat (energy) added to the water to bring it to boiling, this is what affects the food molecules, and not the physical process of boiling itself. This is why you can also grill and fry food without boiling water.
With this technology, is it possible to make a quick, defrosting vacuum chamber to defrost foods?
Thank you so very much. It was so helpful. Thanks a ton!
Thank you very much for clarifying my doubt...
If the vapor condensed to water again would that water be safe to drink? would the air that was in the water return?
Will the water all eventually boil away? Can I use this to dry liquid in electronics without damaging them?
late question, is cold boiling water kills bacteria?
Is it possible to keep it boiling till it all changes phase and then re-pressurize the container and make it flash back to water?
Best explanation
You can’t freeze the water this way. Because at lower pressure the freezing point is also lowered. It’s not zero degree anymore...
Similarly, you can freeze non cold water at a high pressure.
This got me thinking how about dry ice in vacuum chamber.
It would sublime without producing the fog you usually see. The fog you see when dry ice sublimes, is water condensing out of the surrounding air. The CO2 gas that sublimes from dry ice is invisible.
try to test working of beam balance in a vaccum
Amazing explanation.
I am too early to the party, I will return when some Jokers have commented something funny.
Will pasta cook under these conditions or does the water need to be hot?
No. The fact that the water is boiling actually hinders you from using water from cooking, rather than helping you. You want the water to be in a liquid state at as hot of a temperature as possible, in order for it to be effective at cooking food.
This is the working principle behind a pressure cooker, so you can get the water to be liquid at a much hotter temperature. This is also why products cooked in boiling water have high altitude instructions, that require a longer cooking time.
If you put ice in a vacuum chamber would it melt under vacuum and refreeze once pressure returns? May have to do this in a walk in freezer so the temperature stays freezing?
if we increase the pressure several times atmospheric pressure then what happened, will water boils as temperature increased per unit volume pv=nrt
Yes, it will just take more energy to heat the water to its boiling point at said pressure. For example, at 10 bar, approximately 10 times atmospheric pressure, the boiling point of water is 180c.
So when you quickly bring the water back to atmospheric pressure with it at a negative temp Celsius does it freeze immediately
This is as the same thing when you go to a highier place like a mountain water boils much faster,
if you go even highier you will require less energy(heat) to boil the water
