Does Water harden or gel under extreme pressure?

Question

Like in the deepest parts of the ocean? It's understandable that gases would squese out and more solids would fall lower but is there any research public records,that tells what happens at the deepest parts of our oceans under extreme pressure?

If it can emplode a submarine then there has to be other interesting things happening way down under there?

Answer 1

In the deepest part of the ocean water is still water (not ice). However there was just an article in the news (try google) that discussed the properties of water under extreme pressure, pressure far greater than on the bottom of the ocean. It was found that under extreme pressure water will become solid, however the temp will be far higher than 32 F. Actually in the experiment mentioned, water will form a solid above 212 F. Remember, as pressure increases so does temperature, conversely, as pressure increases atoms will want to be in a lower energy state, i.e. gas to liquid, liquid to solid. The article I read, for which have forgoten the title, discusses the properties of water are actually not well known at all, even in everyday conditions.

Answer 2

No, but it can stay a liquid past 32F, without salt. In some glaciers, spelunkers and scientist have seen or observed "super-cooled water" water that is under so much pressure that it moves around too quickly to form ice. The scientists theorize that it explains why some glaciers, even in sub-artic zones appear to melt or shear off to form icebergs.

Water, like any form of matter, obeys the laws of gravity, so when you put water in a zip-lock bag it forms a tear drop shape, rather than a pillow shape like gasses. Or when you stackboxes full of stuff, the bottom ones get crushed, the middle ones bow out and the top ones retain thier original shape. Ice, water, and steam are the same way, how it was explained to me, oceans are like a "bell curve" when it comes to temperature. The surface 15% is the warmest, the middle 80% is the coolest, but the bottom 5% is warmer than the middle, but not as warm as the top, due to pressure and proximity to the earths core.

Answer 3

On earth it's impossible but in Extraterrestrial planet Gliese it is possible. Gliese has an ocean hundreds of kilometers deep below the ocean the pressure is so immense that the water is forced to realign and crystalize. These might also happens in one of the jupiter's satellite Io Pressure increase Temperature but pressure prevents it from boiling until it reach its critical temperature

Answer 4

Due to some recent conjecture on exo-planetary/moon satallite extremes as explained in a few briefs above, the crystallization of water molecules,"H2O" would in fact exist in some of the theoretical ocean moons represented around Jupiter, Saturn, and possibly Uranus, and I would also express that such a crystal would behave much as that of, "Carbon", creating Diamonds. It would be highly valued if Obtainable...:O)
But due to the fact it s presence can t be created naturally on Earth, it would be quite the Gem to Recover, and wow, could actually be an incredible FUEL SOURCE having all the elements for FUSION based Propellants. Quite a ponderance for a material we have such an abundance of, and yet know so little about...lol...

Answer 5

Water vapor can be compressed into a liquid. The molecules are already touching in a liquid so it is not compressible.
Pressure on ice can melt it. That is how an ice skater skates on smooth ice, the fine blase, creates pressure and melts a fine trail.

Answer 6

There is no record about it. But change will definitely occur due to high tempreture and pressure and due to adiabatic compretion which cause change in chemical composition as change of phisical state of coal into diamond. Similar changes is also found in Perl. I think this may help you.

Answer 7

Nope..
Water is virtually incompressible.
Water is still the same at the deepest part of the ocean...

Answer 8

Interesting question! I don't think pressure changes the mass in water - just temperature changes such as boiling (becomes steam) and freezing (becomes ice).

Thanks for forcing me to use my brain this afternoon!

Answer 9

What do you consider severe stress? the bottom of the sea may be at one thousand x atmospheric stress, that's nevertheless liquid. on the finished drinks at the prompt are not particularly compressible.

Answer 10

it remains a liquid, and the gasses are dissolved so they retain oxygen and other gasses...so fish can still breath even down there
