I wonder what sort of pressure a carbon fiber ball can withstand. If I had to guess, I'd say more than brass and less than 43k psi.

Of course they're not, one has 12 zeroes and the other only has one zero.

Indeed. If water didn't expand when it froze freshwater bodies would freeze solid instead of just on top, killing most of the life in them.

We've used it for some pretty interesting construction projects - lifting things, breaking them open, but it's generally too slow for modern society.  Steam is quicker, not easier.

Wouldn't anything at that kind of pressure heat up enormously? That's partly the reason the stun stays explody and planet cores stay hot (like earths, i mean) isn't it? How would it *Stay* ice, then?

This.

And another question(maybe relevant).

The article speaks of decreasing temperature on already formed ice to take it to the next stage.  Wouldn't it take increased pressure before the low temperature is applied and letting the crystals form under pressure?

Otherwise, you're pressurizing already solid bonds which could have a different impact on the structures involved.

I've lost my train of thought a bit, but the article makes it sound confusing.

As to how it's relevant, I think they're talking of lowering temperature in relation to the compacting of the ice.  A theoretical highly pressurized piece of ice would have to be kept drastically cold.

So if you create Ice II , or III or eleventy at high pressure and low temperature, does it change back to regular ice when you relieve the pressure or does the structure remain?
 
2014-01-16 07:31:39 AM  
For fiction writing research I GIS-ed for various forms of ice and got. . . stock photos of hexagonal ice.

I understand the more exotic ones are difficult to create in quantity, but all I'm really interested in is the "hot ice" (Ice VII or Ice X) that would form if, say, Earth's oceans were hundreds of miles deep instead of just a few.  The crystalline structure would be different so it may have a different appearance, but I lack the knowledge to determine how.

Eddie Adams from Torrance: So if you create Ice II , or III or eleventy at high pressure and low temperature, does it change back to regular ice when you relieve the pressure or does the structure remain?


Depends on how strong the bonds are.  Diamond is formed at high pressure, but at 1atm those rocks do just fine because the bonds are very strong.  Considering how hard ice can get, I'd guess -- guessing, mind you, I'm not a chemist -- that most forms of ice are relatively stable.  Watching them melt/sublimate might be interesting, though -- the ice might fizzle and steam like dry ice dipped in water.  After all, even if it's a different substance, dry ice is also created at high pressure and low temperature.
If they're not strong, though, the last thing I'd expect is a nice & orderly arrangement into regular ice.  You're talking about removing the pressure that was keeping the ice stable; if you suddenly removed that the ice would disintegrate in a violent explosion.
