Are hot ice cubes possible?

no.

Nope. Hot water doesn’t freeze.
You could mold a hollow plastic cube and put hot water in it if you want to. I suppose. Then you’d have a hot cube.

Try it. Get some ice cubes and then microwave them.

Yes, if you had high enough pressure, as illustrated here.

@eambos Care to explain that a bit?

@eambos I think you misunderstood that graph, the triple point of water still occurs at 0C. A rise in pressure causes the melting point to go down, not up. So the answer is still no.

Not really. So, it is possible for you to get ice cubes slightly hotter then freezing, by severely increasing pressure. But you couldn’t get truly ‘hot’ ice cubes, since by that point you’d run into some crazy chemical effects. Very cool effects (like a liquid that you could compress nearly infinitly but will still be amorphous), but none you could actually call ice.

On a second note, taking chemistry (or any science) from movies is just a bad idea, kids.

Not if you made them with water.

@Darwin Ah, but if you didn’t, then they wouldn’t be ice cubes

But you can achieve the equivalent with other substances. Why do we have a special name for the solid state of water, and not for other materials?

@BhacSsylan water isn’t the only element you can make ice with.

@ABoyNamedBoobs03 Not true. You can make solids with many materials, but they’re not ice. Ice is frozen water, by definition. There’s other uses, but they’re always prefaced by some descriptor, like Dry Ice.

Baked Alaska?

@skfinkel sounds like a B&J ice cream to be honest…

Hmm, hot ice ice cream… like mayan cocao, but as ice cream?

thinking like a mint chocolate, Cinnamon mix perhaps? toss in some fudge swirls?

hmm. Intriguing…. why don’t i have an ice cream maker!?

Everything is relative. Water at 0 C. is a hell of a lot warmer than any substance at 0 K.

Is it supposed to be like frozen hot chocolate? Because I love frozen hot chocolate. Serendipity 3 FTW!

@aprilsimnel such win.

@aprilsimnel…wow, just wow. I’ve never heard of that before, but wow…

(and now add cayenne pepper… would that work?)

The state of matter something is in depends on its temperature and pressure. If you have high enough pressure, you can get most things to freeze at high temperature.

only to a degree. again, get to high enough pressure, and matter acts in very odd ways, and does not form the usually expected configurations. Ice at high enough pressure would form a compressible liquid before it could be warmed to anything approaching ‘hot’ ice.

No… and don’t believe ANYTHING you see on that movie! It’s entertainment, and all made up.

No, it is not possible. Pressure will not do the trick, as ice has a lower density than liquid water.
