Well, now I just want a video about ice 3
was entirely unaware that there were different types of ice and now I am in need of a video about it
look up Ice Age 3
This is basically the video on ice 3. This is the method used to get it, and the one important property, and how we found out it exists.
Now, another video about ice 2 through 20? :D
There is a video called "Something weird happens when you keep squeezing" by Vox that also talks about these ice phases.
There are *many* different forms of ice. The most interesting is ice-nine.
Wow I didn't know they came out with Ice III already, I must have missed Ice II
Maybe it is like Highlander movies, II was so bad we all consider it never happened 🤔
/jk
"Ice II: Crystal Boogaloo"
Ice II froze to death.
It's ice nine you need to watch out for
There's like 9 different types of ice if i remember correctly
"Oh don't worry, nothing weird happens, it just turns into an entirely new form of ice"
If anyone else is wondering about Ice I and II:
I: Normal ice as we know it, i.e. forming around 0°C and 1 bar.
II: Formed from further cooling down ice I at a high pressure, for example at -75°C and 300 bar
III: As discussed here: Freezing water under high pressure. Can be further turned into either Ice I or Ice II as well.
And then there are like 15 more ice types that form at different pressure/temperature combinations.
Underrräted comment
IX is the best, but requires careful handling
Several of these ice types actually exist inside the Earth's mantle and probably other inside other planets as well.
Above a certain pressure, when talking about gigapascals (GPa), eventually most things become solid, no matter how hot they are, and this includes water as well.
I love the theorized metallic water/ice. But since it needs terapascals...
Ice VII (7): Let's apply a ton of pressure to normally liquid water
Not mentioned; when doing this in real life, those pressure numbers get terrifying really fast. The ice desperately wants to form and will rip steel pipes apart, freezing instantly as it finally has room to expand.....hence pipes busting in winter
600 atm are 607 bar and that is the number for -4°C. a car tire has around 2 bar.
Electrostatic forces are damn strong...
Does a container that can withstand those pressures really exist?😮
@@richardgratton7557 Yes you just need a really thick container.
@@richardgratton7557 yes it does exist but only with a very small volume where the pressure exists. it is basically a round steel ball with 10+cm wall thickness and a highly specialized valve. also another trick to do it is putting the high pressure tank inside a not as high pressurised tank so that the pressure difference between inside and outside isn't as extreme.
Wait, how have I never heard of Ice III before? I feel like we need a video just on that.
It's just a slightly different crystal structure that is only stable under very high pressures. So you can't really do anything with it.
It is not so odd considering people generally just come in to contact with you regular ice, water and vapour/gas. The other forms you generally see in just extreme conditions.
From Wikipedia, there are 19 ices in total en.wikipedia.org/wiki/Ice#Phases
@@Cythil but extreme conditions are extreme just for our common perception, lets say on some other planet or in some point underground they can be pretty "normal", so we must not judge on that just beause we don't see it regularly around us
@@5poolcatrush extreme = something outside what we consider normal. That's not judging, it's just convenient use of language.
That's why the term "incompressible" is a bit misleading. Water can be compressed, it's just that even a tiny bit of compression results in absurd amounts of pressure, since water molecules (or any liquid particles) push back against each other VERY strongly when they get close. Electromagnetism is a crazy strong force.
the term itself is a bit misleading since pretty much everything in the universe is compressible if you apply enough force
You: ha, I will hack universe!
Universe: no you don’t.
Ice melting under pressure is oddly relatable

Learned in undergrad chemical engineering ice actually has 18 crystal structures (aka building blocks and they’ve actually found an ice-19) in which it can form depending on the surrounding conditions. Truly fascinating!
Another fun fact the way iron forms it starts out bcc or body center cubic and at higher temps it switches to a fcc or face centered cubic structure and you can physically watch a piece of iron change it’s crystal structure
For y’all surprised that Ice III exists alongside Ice II, you should probably know that Ice VII (7) exists as well. Idk how much higher the numbers go lol

Is Ice 3 a final release version, or is it still in early access ?
@@scratchy996 it’s actually been out for a while, just a bit under the radar. Not as popular as the other ices, but still holds its own against them.
I asked this question about 25 years ago in my first ever high school science class. The science teacher went and got the chemistry teacher. He thought it was a great question but he didn't know what the actual answer was. I've never stopped wondering! I hope he's still around, I'll send this to him and see if he remembers me asking all those years ago.
@@mileyardgigahertz we don't, trust me! That was one of the best ones in a school full of very good teachers. I had just finished at a school down the road and it was full of the teaching rejects. Awful school. Maybe someday I'll write a book but probably no one will believe it!
@@mileyardgigahertz The majority are just doing a job - not passionate about teaching like mentioned above. Passionate teachers in the US exist, but they are the exception. However, those that are both passionate and good at teaching subjects leave enough impact on the students that the students remember and talk about them later, so you hear about them. No one wants to remember the bad ones.
I have had my share of good teachers, who cared about teaching and bad teachers who cared about nothing, except keeping their job.
I would say the main difference was that the great teachers, where secure in their living situation. No matter outcomes of students, and they only taught because they loved it.
I also realize that I was only in good schools where teachers made living wage and students where raised well and respected teachers.
Mileyard American teachers are overworked and underpaid like everywhere else.

Solid ice phases are actually extremely interesting, and there are quite a few of them. It's a fun research topic to expand (ha) your knowledge about crystalline structures and phase transitions.

They are extremely interesting. Especially when you try to learn about all 19 phases of water ice.
@@v44n7 idk about usefulness, but those exotic phases of ice probably exist on icy/watery worlds. Even in our Solar System.
@@blockchaaain Yep in fact they have found inclusions of ice 7 within diamonds brought up from Earth's mantle so even on Earth there isn't just ice 1 naturally occurring if you look deep enough down
Best explanation of a phase diagram, very well done.
If you lower pressure enough, the boiling point will decrease, so there is a point where if you freeze water in a low pressure environment, it will attempt to boil and freeze at the same time
This is actually a useful property. Freeze driers work by freezing a thing and then dropping the pressure so much that the ice evaporates rather than melting
A long time ago I read a scene like that in a sci fi book (can't remember which, more's the pity). Some aliens drop a bomb onto the surface of Europa, shattering it. The water underneath boils and freezes all at once!
I think this deserves a follow up with the complete water phase diagram.
That's a whole thing, probably longer than a minute, as different solid phases aren't concepts that just apply to water. For instance, common iron is known as alpha iron, while high-pressure iron can turn into epsilon iron, or hexaferrum. Carbon can be graphite or diamond. Oxygen has 8 different solid phases.
The mechanisms involved in the creation of these are the exact same mechanisms that lead to the creation of ice III. The particles just pack into different arrangements because they don't have enough space to do what they'd do at the temperatures & pressures that we're used to.
@@KazmirRunik Dope
@@KazmirRunik And don't even get started on phase diagrams of mixtures (Iron-Carbon for example) at which point the number of possible phases "explodes" depending on how mixable the constituents of the mixture are.
Oh the sweet memories of having to memorize the entire Iron-Carbon-Diagram at atmospheric pressure and be able to draw it in the exam. Material engineering ftw! :D
Complete with supercritical water
Yeah, I would like to see the video on water in the vacuum of space.
I think the most exciting phase of water is Ice IX, as described in a paper by K. Vonnegut, J. Jonah and K. Trout, appearing in the Summer 1963 edition of the journal "Cat's Cradle".
This video reminded me of this classic too! Great research paper 😂 also digging into weird banned religions that seemingly everybody practices

It's great to have your share on this.
Please do a follow up video on the different kinds of ice and how they are formed. They are so interesting, I searched them up one day when looking into what would happen if a huge planet was made entirely of water, and the pressure would make interesting different kinds of ice like ice III. Seeing other comments, it seems others are interested in the different types too.
Even cooler is that is technically possible if a planet is close enough to thier star to have a planet of ice that is on fire
@@mauricebenink Yeah, some ice only forms when it’s hot. And some only when it’s cold. And some under very low pressure, and some under enormously high pressure, it’s interesting just how many conditions will form ice.
I think I don't remember. Wasn't it ice 7 that formed 'hot ice' you could call it. I remember a lot of numbers being jumped over
I think there is at least one actual exoplanet like that.

This is actually really hard to do though. You need super strong metals like you said and super strong joints and then there is the issue of how the container is closed. ... like threads are weak etc etc.
Now I understand at a basic level the different versions of ice. Cheers 👍
I’ve seen others try it, it mostly involved the (metal)container bursting open as the water froze
1850 bar is a lot of pressure. For a cylindrical mild steel vessel, you'd need about a 2.5" outer diameter to support a 1" inner diameter solid pressure vessel.
the whole point of the thought experiment is that it can handle much higher pressures than the random stuff you find around your house or even chem labs.

You’ll come to regret calling it simple… the basics are but you’ll find out it’s a lot more complicated but even more interesting 😊
This is a well, "Brilliant" 🙂 explanation of a very unusual corner case in physics. Thanks for sharing!
In the extreme, the pressure on the atomic structure, if not allowed to crystalize, will force a fracturing of normal space, into subspace, causing a rift in the space-time continuum. This can be contained using a static warp shell. It can then be successfully repaired by hitting it with a focused inverse tachyon pulse.
I heard back in like 2019 in some TV show(Discovery channel I think) that there are 7 different such types of ice, all at different pressure and temperature conditions. This gave me some nostalgia.
there are 18 differjt rypes of Ice...

unrelated to the main topic of the video but i love how the music sounds like the music that plays when theyre drawing in the notebook on blues clues lmao.
I've been wondering this for literal years. Thank you.
its amazing you are still dropping classic videos after all these years. kudos people will be watcing these videos for decades.
I've actually seen an example of this recently! I put a can of pepsi in the freezer just to see what would happen.
At first it expanded and the can bulged out, and I assumed it had stopped expanding and all the liquid had frozen after a couple days. But then at some point the can burst, and sprayed liquid pepsi all over the inside of my freezer! When I looked inside, it kind of looked like it had formed horizontal stalagmites on the door of the freezer, almost as though it had frozen instantly upon touching the wall or even in mid-air, which makes sense considering it would have been below the freezing point by then, and would have gotten even colder when the can burst due to the sudden expansion of the pepsi!
Yep, a related concept is that of "superchilling". A liquid can be superchilled well below its freezing point but still stay as a liquid, but when some sort of external force or agitation is undergone, it will suddenly and almost instantaneously freeze.
@@LittleWhole Even more interesting is that a type of hand warmer uses superchilling to produce heat. Not the most effective thing but still interesting nonetheless.
@@ragingfirefrog I actually have a few of those reusable hand warmers, very useful where I live since its so cold in winter.
The soluabilty of a gas in liquid varies inversely with temperature. So the pressure from the CO2 would decrease. But afaik it is not dissolved in any ice that forms. Which means the pressure increases as there is less liquid to dissolve the gas.
I forgot 3 energy drinks in the freezer. A Coke Energy, a Burn and a Red Bull. The Coke and Burn broke the can and froze. The Red Bull didn't freeze. It looks like Red Bull is so toxic, it contains anti-freeze instead of water.
On frozen over lakes you can see, when its cold enough, that cold ice has higher density then warmer ice. The top surface will show hollow dish like shapes with surface cracks. At atmospheric-ish pressure this should be visable from around -15°C and colder. The exposed to air top layer shrinks while the lower, exposed to water layer does not. Also the thickness of the ice should not be too much. Thicker ice is more resiliant to this dish forming effect.
Also note that Very high pressure ice also melts at a higher temperature.
For example from about 6k bar it's melting temperature starts dramatically increasing. At almost 100k bar it is frozen and that type of ice only starts melting at about 330c. More pressure and temps keep increasing for melting point.
Of interest if the pressure is dropped some types of ice (formed at High pressure) at 1 atm will still have an increased melting point mildly above 0c. From memory of a documentary many Years ago it was somewhere between 3 to 7c but don't hold me to that part, but is about right I think - bit tired at the moment. They were doing experiments with a diamond anvil cell.
Fascinating. I’d heard that people had discovered a bunch more phases of water/ice, but I had no idea there was one which contracted instead of expanding, and this explanation of how you get to it is great!
Please make a video about Information Paradox (and why information can't be lost)
"If Ice is so cool, why haven't have made Ice II yet?"
Physics: "Bro we're at, like, Ice XIX right now."
You can also boil water at very low temperatures like 140 degrees farenheit, we used "vac boilers" to clean out old printer cartridges at one of my old jobs. the boiling happens and creates amazing agitation but the water is only 140-150 F so it doesn't damage them
I boiled water at that temperature by sucking some up in a syringe, blocking off the entry hole, and then pulling on it. The inside space increases by like multiple times, which decreases the pressure, and the water boils
At first the syringe wants to collapse but if you hold it at the expanded position eventually the pressure from the water vapour makes the stretched position the "default" instead of it being forced
I’ve heard about stuff like ice 7 that’s alleged to make up the sea floor on planets with remarkably deep oceans and been found on earth too by diamond mining operations. Idk if it’s more or less dense than water though but definitely denser than regular ice
I think the gas giants have some. Although they have way more liquid hydrogen than ice anyways.
@@solsystem1342 Gas giants are supposed to have Ice XVIII (18). It's pretty wild. It's basically an "anti-metal" or something. Instead of having a lattice of positive metal ions in a sea of electrons, this has a lattice of negative oxygen ions in a sea of protons (hydrogen ions).

@@HercadosP like nothing probably, polar compounds are probably an important part of what even allows chemical compounds to have enough degrees of complexity to make life happen
@@Ivancal72 They're mostly different ways of arranging the water molecules into crystals.

i dig the solo double bass in the background
this is a question I've pondered about in the shower for years.
Thank you.
I was just wondering why didn't you post anything new for a while. Love what you do. Keep going ❤️
I think the first time I had ever heard there are different phases of ice was reading about a hypothetical planet's ocean being an order of magnitude deeper than Earth's. The pressure found deep in this ultra deep ocean forces water to freeze in this manner and forms the seafloor. For a planet the size of Earth I think it's around 65km in depth to get like this.
I think I've seen the same video, because after reading your text I suddenly came to the realisation that I also first heard of Ice-types in such a condition. Thanks! :)
Hmm... Ice-1 is barely less dense than water. If Ice-3 is denser than water, seems like it would build up on the seafloor over time, potentially causing any number of awkward problems!
honey, come quick, ice 3 just dropped

Water, one of the most simple and common molecules around us, is actually one of the most complex behaving molecules we've studied.
I love learning but I love cheesy puns more! Henry, so many bonus points!
That ice-suspect kept me watching til the end of the video.
We were taught something like that in physics. I know that an increase in pressure decreases the water freezing point, from zero to some negative, depending on the new pressure. There's even an equation that includes temperature, pressure and volume
i think that below a certain depth in the ocean, it is techniqucally below freezing but due to the pressure it doesn't freeze. i heard something like that on an attenborough doc, or it could have been that water around hydrothermal vents were many times hotter than boiling but couldn't due to pressure.
Ive wondered this my entire life. Thank you
sounds like you would really enjoy watching some lectures on intro materials science! phase diagrams are super cool!
I got a question:
If you got an object which the mass is just below the mass needed to create a black hole, you take that material and you accelerate it by like, throwing it really fast or not.
*Will this material become a blackhole?*
Since e=mc^2, yes. But no.
I like the way you think, keep being curious.
No. Mass doesn't increase with speed, gamma does. Here's a video explaining it very, very well: ua-cam.com/video/LTJauaefTZM/v-deo.html
Edit: Gamma, not Lambda.
@@SlimThrull Thanks for the video 👍
@@SlimThrull But if you increase the speed, the material will colide with the air and it will increase it's mass if the molecule in the air sticks to the material
This helped solidify my understanding of triple points
I’ve pondered this question for years and nobody’s been able to give me a solid (pun…intended?) answer. Thank you for this!
This is a great video, it explains phase diagrams really well, I think maybe the only criticism is that the word "equilibrium" would've been nice at the end, as often when you get an apparent paradox point in a changing system, what you really reach is an equilibrium (forces influencing one way equal forces influencing the other).
What I will say as something you've taught me, ICE III CONTRACTS? I knew different types of ice existed and had differing properties, but it contracts, that's wild. I would love a video on the different types of ice honestly.
Well, most substances contract when solidifying, water is the exception, and it's the reason why the phase diagram is different for it as well
Almost every material contracts as it freezes. Water happens to have a unusual (near-unique) combination of a relatively dense liquid phase (due to hydrogen bonds) and the least dense solid phase it can given its bond length (different crystal structures have different 'packing factors' and ice Ih is the least efficient of any of the common crystal structures, if I remember correctly), and even then the efficiency difference is quite small and ice only expands by like 10%. But other ice phases have other crystal structures (this is actually the primary way a crystal phase is defined), which I think all have higher packing factors than ice Ih. So, pretty much every other phase of ice is denser than regular ice, and I don't think there are any others that are less dense than liquid water. There are like 18 of them and I didn't check them all.
There are other materials with the same crystal structure as ice Ih, but their liquid phases aren't as dense as water's so they still contract when freezing, just not by as much as some other materials.
For some reason the actual packing factors of various crystal structures are incredibly difficult to find online, outside of the 5 most common crystal structures that metals and stuff have. I can't find ice Ih's packing factor at all and I've been looking for like 30 minutes. You'd think this would be a pretty basic thing, as it's a very simple geometry problem, but I can't even find the parameters I'd need to calculate it myself.
@@Archimedes.5000 Ice 3 contracting is like North Korea becoming more democratic. It's normal for other countries, but still very strange for North Korea.
Contracting while solidifying is normal for other elements, but very strange for water.
Wow, this remind me those when as soon you open a sealed bottle of water it freezes completely. But also we can do the opposite bt bolling water on a fully airtight bottle and toss it in the fire, I used to do that on some camping trips when we forgot to bring kettle. Pressure can do wonders if you know how to take advantage from
Thank you for this. I wondered about this for years as a kid.
This is very cool (ha). I first read about this years ago in a book self-published by a cranky ex-meteorologist in Oregon. He was explaining supercooled water and showed how, for a tiny droplet of water in a cloud, surface tension is enough to keep the water liquid below freezing. This is what makes these clouds so dangerous to airplanes.
i would love that you included a clip of what would have happened if the container can't withstand infinite pressures.
Busted pipes in winter is what it looks like 😉
you just gonna gloss over the fact that there is apparently an ice 3? tell us about the magic ice!
Waitll you hear about ice-9!
There are far more (water) ice crystal structures than just 3.
There are 18 known phases of ice. Probably more unknown ones.
Lol. I had just completely learned phase diagrams for Steel- Fe3C, and it became obvious right away what will happen, although with iron, we can ignore the pressure because it doesn't do much with solids, thus we can use the Gibb's phase law with just +1 , but with +2 when it is water . Nice video!
It amazes me the pressures that system can reach.
Interesting side fact: because if the low surface area with the body weight of a human, skates cause the ice bellow it to melt which is what causes you to glide so smoothly.
iirc this has been partially debunked - ice below some temperature (minus 6 Celsius or something?) can't melt enough to support skating through pressure melting alone, so there are other effects that help skate
considering the surface area by weight of my ass, ice can support a skater quite well.
I feel like we need a video on every phase of matter water has
That is going to be a long (but awesome) video lol.
I'm lost right away. Water can melt? lol.
2:04 so this is where Ice-9 in Zero Escape 999 comes from?? :O
Ice-9 originally came from the book "Cat's Cradle".
@@WilliamLeeSims ...which came from this
Imagine the meeting where the CEO demanded that unlike other materials, water has to expand when becoming solid, and then the engineers went like, but what if it can't expand and they went over different scenarios and chose this and after that a bunch of senior engineers quitted but it became a good product in the end.
Ice3 is just version 3 of ice, after 2 major iterations, all the bugs have been solved.
Ice 3 will be successful but ice 4 changes to a subscription model. Ice 5 is then bought by EA and from then on ice 5-20 are just annual releases that look the same.
this whole ice iii business is a brand new world to me, guess I have some googling to do later! loved the ending haha
another interesting point is where the three lines of the phase diagram meet: the Triple Point where water freezes and boiles simultaneously
or how dry ice goes from a solid to a gas.
Before : so there's a paradox here
After : There exists something called ice 3
Me: that's cheating
So what happens if you take ice III and reduce the pressure but hold temperature constant? The phase diagram says it'll turn into ice I. But what does that look like? Will it suddenly explode into snow or what?
i haven’t started the video yet but i’ve wondered about this question for the longest time
of all the answers i was expecting for this problem, trans rights for ice was not one of them
You blow my mind dude
what would it look like on P-V diagram? i think it's more helpful to see it there since's isochoric process would be a vertical straight line. but i guess it would be harder to illustrase the temperature lines, since most people would imagine cooling or heating with temperature changes.
There’s actually higher ice numbers too but it gets very technical
Water is like this very mystical compound that seemingly defies the laws of physics
All the way back in the late 90s, the EU did a huge study to compare the quality of school education between member countries by letting kids take a number of voluntary, non-graded exams on a wide range of subjects.
I was one of the kids selected in Germany, and the one test question I remember was to write a one-page reply to the question "What would be the effects on nature if frozen water did not float?"
And it's really easy to fill a page once you start going down that rabbit hole.
Why would anyone think there was a paradox here and not simply that it'll reach equilibrium?
The 'Preface paradox' is a whole big thing about how a book noting that it may have errors in it is crazy. The 'Temperature paradox' is literally 'The temperature is rising. The temperature is ninety. Therefore, ninety is rising.'
Paradoxes as a whole can be astoundingly dumb.
I remember studying this in college, Mostly I remember learning about the Triple Point. Water is definitely more interesting than most people think it is.
Didn’t know that! Thanks for the knowledge
I'm rooting for Ice 9 (RIP San Lorenzo Island)
Damn Ice 3 is already out? I havent even tried ice 2 yet :(
Does this relate at all to snow compressing and freezing blue in a glacier? I always thought that was neat having super dense ice with very little trapped air
I always wondered what happen if you expand a metal ring, then put it on a rod snugly and then let it cool down. Will it snap the rod? Will it cool down slower?
So... what happens when you open the container with the highly pressurized, but solidly frozen ice?
Depends on the temperature. It either melts or sublimates. Just look it up in the phase diagram.
It would probably just spray out , did It with gallium and a steel ball : ua-cam.com/video/bAlGdTTk7Kg/v-deo.html
If it's close to the melting point (at that pressure!) it will quickly form ice I, expanding significantly quite quickly. If it's colder then ice III is more stable and the transition is slower.
Wait wtf is ice 3???
It's a different crystal structure of ice, than the standard ice you normally experience.
When you've just taken a thermodynamics exam and minute physics decides to bust through half your course in one video
ive been thinking of something similar for a while now, you know how when you put borax into hot water it turns into crystals that attach to the surface of the container once it cools down because hot water can hold more sediments than cold water, and the excess borax to go somewhere? well what if you did that experiment on water that wasnt held in a physical container? like what if you did it in zero gravity in space in a ball of water just floating around? where would the crystals form?
the enby jokes earned my subscription and made my day thabk you
I was looking for something like this
Non-binary is also just a regular phrase to refer to something which has more than 2 options.
Cool
Hmmm, makes me wonder what happens to water under pressure without anywhere to escape or room for it to expand and turn to vapor? How long would the container remain hot? and How hot for how long? Just wondering if that could somehow be used as a long lasting heat battery. I'm sure the energy lost through the container as heat will affect the system but how and what would that do?
This channel is the embodiment of “I don’t understand but it sure hell is entertaining”
Keep in mind that this is under the assumption that the ice/water system is maintained at a constant temperature. There is also latent heat of fusion involved. If your container were INSULATED from any transfer of heat, then as soon as any water would freeze, it would heat up the surrounding water since crystallization is an exothermic process. That heat would transfer back into the ice, allowing it to melt again. So a thermally isolated system would undergo no phase change. Everything in this video assumed temperature constant, which would actually require you to pump heat away from the system to get it to freeze still.
neglecting friction :D every text book does it. but good point you have to state your assumptions.
Fairly low level chemistry but despite knowing the concepts (I mean, I have a degree in it...) oddly satisfying to watch. Thanks!
Freezing water causes a hell of a lot of pressure, though - I remember a demonstration photographed in a Time-Life book (circa late 60's) in which a thick, hollow cast iron ball (about 5-6" in dia) was filled with water, sealed with a screw-in plug, and lowered into a tub of liquid nitrogen, This was done in a small observation room with a remote, robotic winch controlled by a scientist watching through a small, thick, shatterproof glass window. After a few seconds of immersion, the cast iron ball exploded, with shards of it getting imbedded in the steel door to the observation room.
Didn't know ice could be this interesting of all things
