you have definitely improved your knowledge and understanding of science and chemistry in general since your first few science experiment videos. great job!
It actually "dissolves" faster, because the water that "touches" the glass directly cools down faster and sinks to the bottom of the glass. Water from the top floats to the place where the cool water was and the process repeats. It's calles convection. Just google for it and you will find some nice visualization. Though most household "chemicals" like salt, sugar dissolve faster in warm water, there are a lot of substances that dissolve dissolve better in cold water. It's because some dissolvation processes produce heat when they occur and others absorb heat.
It is a combination of 3 things. 1) convection current by the hot water rising up the middle and sinking down the sides where its cooler. 2) diffusion of particles within the water 3) heat creates more energy and speeds up mixing by making particles move around faster meaning faster mixing.
Come on, man, enough of these elementary school science experiments. Stop trying to be Mr Wizard and go back to being the Crazy Russian Hacker. You didn't get a million subs from doing this kind of stuff, you got the subs for doing HACKS that are actually useful. Can you go back to doing that, please?
I heard this from a professional chef. ad hot to cold or cold to hot for ease of incorporation. say you are adding cinnamon two eggs for French toast if you just add the cinnamon it will not beat into the egg. But if you mix the cinnamon in a shot glass with warm water then added to the eggs it will distribute evenly. hot to cold makes great sauces. Another good video CRH.
You could have saved everybody on the planet a full 2 classes of chemistry with the sentence, "Why does this happen? It is very simple: it is because water is made of particles that are always moving, so, the hotter the water, the faster it moves."
Actually it is because of the densities of each one. In hot objects, particles move faster, causing that object to be less dense than a cold object with less particle motion. Therefore, in the hot water there is more space between particles for the ink to move and dissolve into.
It's because when atoms and molecules are heated, they have more energy and therefore more kinetic energy, therefore they're moving around a lot more than cold atoms and molecules, therefore with more movement becomes more collisions with the ink particles meaning it diffuses out a lot easier, causing it to spread like seen in the video, it's all pretty cool stuff
I would say it's not as much Brownian motion as it is the cold ink sinking quickly in warm water, but as it sinks it's warming up and the lower ink stops sinking. This differential in sinking rate may cause some turbulence that does the mixing.
Can someone please please please help me? I have homework and I can't find an answer to these questions: How has Brownian motion affected our lives? Is it a good or a bad thing and why? What factors affect the impact of this? What real life implications does this have?
I suppose it's the same affect as mixing sugar in hot water vs mixing sugar in cold water. The sugar will dissolve faster in hot water, and you could dissolve more of it than in the cold water.
Earlier today, I experienced that. I put some ghost pepper sauce in water, and the sauce just clunked together and did not disolve. When the water started to become hot enought, the sauce began to disolve, and the vapors made me choke a bit... And then, my kraft diner was spicy and good.
'the harder particles are the faster they move' ? probably he meant the faster they move DOWN, because if harder then more inertial, consequently slower.
obliviousfafnir01 From what I read, water that is in an excited state loses its energy far faster than water that in a less excited state. The energy that's keeping the water in its liquid state is more readily available to transfer than when it's cold. Here's a link to a famous example of what I was talking about. Instantly turn boiling water into snow. watch?v=62Hos_utIAs
Есть проблемка. Основной видимый эффект не из-за Броуновского движения, а из-за конвекции. У охлаждаемых стенок стакана образуется более холодная вода и она из за более высокой плотности устремляется вниз, а в центре стакана образуется восходящий поток. Движение воды и ускоряет перемешивание.
that's not JUST due ti brownian motion, the temperature also make a difference... obviously the ink temperature is closer to the cold water than to the hot water. So, in such case when the temperatures of 2 liquids are too different a fast displacement happens (exactly like how mixing hot air and cold air will cause a wind) which is what you see in the video. Thue test would be to have 2 inks: one hot and added to the hot water and the other cold and added to the cold water; this would then show the brownian motion more acurately (ignore the density difference...).
I don't think that is classified as Brownian motion. It is a very small movement. I think that it is due to convection currents caused by the outside of the glass cooling and going to the bottom of the glass. This doesn't happen with the "cold" water since it may just be room temperature and be without the thermal difference to cause convection.
Hey CrazyRussianElemtarySchoolTeacher, ink doesn't dissolve in water, it diffuses in it. Please learn your terminology. We don't want ignorance to spread around even more than it already is. -_-
I think it's because the water is warmer, and the distance between the particles is larger so the ink can dissolve in the water more easily. And the convection currents in the water might be faster in the warmer water, making the ink move around faster. Maybe it's not, i dunno.
or just "Entropy" Entropy is the natural tendency toward disorder which is favored by heat due to increased movement of the particles (bump into each other more) and in turn spread the ink around.
Sorry for being a jerk but actually water is called the universal solvent meaning it can dissolve pretty much anything and the hotter something is the easier it is to dissolve. For example put some warm milk in the microwave and heat it up. Then mix in some hot chocolate mix. Now repeat with a cold glass of milk and see which dissolves the coco mix the fastest. One more example is that people put tea bags in the kettle or cup when the water is hot so it dissolves a lot faster. :D hope i cleared it up a bit not trying to be a hater he works hard to mKe these videos. Keep up the good work!
Also, if you notice in the hot eater glass, the ink rises at the center of the glass and sinks at the sides. Also, did you know the water starts freezing at 4c degrees? Also at this temperature water is as dense as it could possibly be. Also I just noticed that I used the word also 4 times. 5 times actually.
The water is warm causing the molecules in the water to be more active thus cuasimg the ink to desolve rapidly. the hotter the water the quicker it will dissolve.
what temperature was the ink compared to the "hot" and "cold" glasses. id like a follow up video on hot ink and cold ink in hot water and cold water and for that matter warm and precise temperatures for experimentation.
He forgets about convection currents, as heat from the water disperses onto the table...(as the table is cooler) the water will turn in a circular motion, further mixing the solution
i actually like these kinds of video, what's the point of doing bigger science experiments, for the wow appeal if a lot of people don't know the basics first, rite?
Damn if science classes in school were like this I'd have actually enjoyed it/learned something. Perfect visual representation of particles moving at different speeds for different temperatures. Thanks.
you have definitely improved your knowledge and understanding of science and chemistry in general since your first few science experiment videos. great job!
its been 8 years since you commented this, how is it going how is life
i think you are 22 now

O.K. It's "hot water"!
I was hearing "hard water"…
It make sense now…
Same here bro 😅
.🤣
istg aahha
It is a combination of 3 things. 1) convection current by the hot water rising up the middle and sinking down the sides where its cooler.
2) diffusion of particles within the water
3) heat creates more energy and speeds up mixing by making particles move around faster meaning faster mixing.
1:30 and they all be smoving
😂😂🤣🤣
I just had some Brownian motion in my pants.
Elaborate please...
@rajvanshiaditya Well, it was messy, and I needed to change them as much as I need to change my diet.
I like how this looks in cold water . I also like that you have an explanation about why it happens the way it does . Thank you
I watched a chicken cross the road today. It was poultry in motion.
I am sure I have seen you before somewhere...
Are you high? xD
lol i got A+ for this experiment
We dont even have experiments like this at my school :(
your "i'm undressing you with my eyes" look definitely caused some motions. LOL.
Come on, man, enough of these elementary school science experiments. Stop trying to be Mr Wizard and go back to being the Crazy Russian Hacker. You didn't get a million subs from doing this kind of stuff, you got the subs for doing HACKS that are actually useful. Can you go back to doing that, please?
Amen
i didnt do stuff like that in elementary school! :(
***** You didn't do food coloring in water to learn about diffusion in grade school? I'm sure you did, you might not remember.
100% agree with you
albara BB ^^
More life hacks! :D
Brownie in motion is when you throw a brownie in the air
And catch it with your mouth
Wait! So brownian motion isn't when you shit yourself
if i could give you a hundred thumbs up i would :P

No pipette ... I am so sad to see that this science guy doesn't have the proper tools...
Bongos Soviet Union always has shortages.
I showed this type of experiment to my kids last year!
It's a good way to explain how water molecules behave when heated.
I think it may be convection currents in the warm water caused by the difference between the water temperature & room temperature
Science experiments are awesome. Keep up!
Very good. Your school physics teacher would be proud of you! Keep up the good work, I love your videos.
Thanks God he was wearing glasses

it really isnt related to temperature (movement of particles).im guessing it has more to do whit convection currents.

CrazyRussianHacker for UA-cam Personality of the year 2014! :)
I never done this before haha :) it be cool if we could see some more life hacks on how to make the perfect samich
I suppose it's the same affect as mixing sugar in hot water vs mixing sugar in cold water. The sugar will dissolve faster in hot water, and you could dissolve more of it than in the cold water.
you " crazy hacker " have the knowledge and understanding of a science student in grade 5 in US .....
wrong
Just because he is doing science doesnt mean he has to do something really complicated .
Learned about this at school. Didn't understand a thing. Watched CRH's video. Understood it.
crh didn't even explain this well. if anything, he explained it incorrectly lol.
Earlier today, I experienced that. I put some ghost pepper sauce in water, and the sauce just clunked together and did not disolve. When the water started to become hot enought, the sauce began to disolve, and the vapors made me choke a bit...

Hot water freezes faster than cold water. It also freezes clearer.
How do you figure?

Life saver. Our teacher gave us this assignment and I was miss a food colouring
Everything you are teaching me I am learning in school right now lol but I must admit you teach it better than my science teacher

I think you mean "diffuse" instead of "dissolve".
Our teacher told us to 'research a brownian motion experiment as your assignment.'
3) is basically a link to number 2. It just speeds up number 2 faster than cool water.
I don't think that is classified as Brownian motion. It is a very small movement. I think that it is due to convection currents caused by the outside of the glass cooling and going to the bottom of the glass.

Почему бы для того чтобы вылить столько сколько нужно капель не использовать ПИПЕТКУ?
Hey CrazyRussianElemtarySchoolTeacher, ink doesn't dissolve in water, it diffuses in it. Please learn your terminology.
We don't want ignorance to spread around even more than it already is. -_-
But he didnt say dissolve. He said Jizz'zolved
That's called Diffusion, and the diffusion rate can be change, like you said when the particles move faster or slower
I think it's because the water is warmer, and the distance between the particles is larger so the ink can dissolve in the water more easily. And the convection currents in the water might be faster in the warmer water, making the ink move around faster. Maybe it's not, i dunno.

Entropy is the natural tendency toward disorder which is favored by heat due to increased movement of the particles (bump into each other more) and in turn spread the ink around.
After 7 years, here I am again watching one of your videos. Hahahaha
I vote for the convection of the cooling water. Brownian motion is too delicate to speed things up like that.
thats why they say sugar disolves better in hot water than cold
"That's why they say", law of nature bro, statistical mechanics.
TheAmmoniacal sorry, i means that why it happens...
Sorry for being a jerk but actually water is called the universal solvent meaning it can dissolve pretty much anything and the hotter something is the easier it is to dissolve.

Could you do the hack where you use your laser pointer as a macro lens for your camera phone.
Came from studying kinetic theory, This effect was observed in the 19th century. Ty for posting
I could smell the ink :p
Your avatar implies that we probably shouldn't do the same. XD
u never out of ideas
These experiments are getting easier and easier
This is REALLY going to help me in a zombie apocalypse, amazing
Also, if you notice in the hot eater glass, the ink rises at the center of the glass and sinks at the sides.
Also, did you know the water starts freezing at 4c degrees? Also at this temperature water is as dense as it could possibly be.
Also I just noticed that I used the word also 4 times.
5 times actually.
I thumbed you up because of your accent. Wait that didn't come out well. Wait, what?
Brownian motion...Yes. But...There are more convection currents stirring up that hot water. Which causes the most mixing? The convection...
The water is warm causing the molecules in the water to be more active thus cuasimg the ink to desolve rapidly. the hotter the water the quicker it will dissolve.
Because the hot water molecules move fast so it dissolves fast but the cold water molecules just vibrates or moves very slow
extremely cool demonstration of the molecular movement.
ten thumbs up!!!!!
Everything reacts faster in a warmer environment. whilst in a colder environment things react slower
SQUEEEEE! I love you too, Taras
I love your videos ... I didn't understand it from my book but your teaching is so easy to understand 😃😃 thanks
Them particles is always movin'
Why don't u just use a dropper -_-
what temperature was the ink compared to the "hot" and "cold" glasses. id like a follow up video on hot ink and cold ink in hot water and cold water and for that matter warm and precise temperatures for experimentation.
Crazy Russian Hacker you still remember 8th grade lessons
Molecules*. Particles are stuff inside the proton of the molecules. And inside that are superparticles
So it is better to wash out ink with hot water then from the clothes right?
BLOW SHIT UP LIKE A CRAZY RUSSIAN!!! DO DANGEROUS STUFF!!!
Interesting:-) I like experiments just as you like, haha!
He forgets about convection currents, as heat from the water disperses onto the table...(as the table is cooler) the water will turn in a circular motion, further mixing the solution

this man is the reason i’m gonna pass physics istg
Love what your doing CRH, keep it up!
That is diffusion.
0:47 the ink in the left cup made the shape of a rhino
Atomism and Scientific materialism will prevail!
I'm gonna have to try this very soon, but with a friend!
thanks for explaining your recent experiments. :)
this experiment gave Albert Einstein the nobel price for science!
photoelectric effect....
Enjoyed alot
But watching ur actions and listening to ur russian english👍✌
I was thinking that the hot water forced the more dense ink down and was creating a mini current to mix up the ink.
lol wtf
Hot rises/sinks faster cold doesnt. WOW I never went to the 1st grade and im sure i missed this. Thank you for the 1st grade lesson.....
try doing an experiment with more glasses of water at different temperatures.
Jorda bhai bole to jakas
I guess this isn't Brownian Motion. This is due to convection currents present in hot water.
Actualy its coused by thermal convection pushing around the water to make it dissolve.
Damn if science classes in school were like this I'd have actually enjoyed it/learned something. Perfect visual representation of particles moving at different speeds for different temperatures. Thanks.
I came here just to see how he would pronounce Brownian :D
Looks like the motion in the warm glass is from convection currents that are mixing it quickly. That's not Brownian motion!
welcome back to im all about toy
Whats up everybody welcome back to my labretory where safety is number one prrrrorittyy
Love your videos!
Im still surprised how many subs this guy has.
your a really good guy. thanks man
You should use eye droppers for experiments like this.
