what will hapen if we put 1 litre of water, under a huge presure, for example 1 million bar?

Answer 1

Where is fllodtl when we need him?

Phase diagram of water under high pressure
is shown here:
http://www.lsbu.ac.uk/water/phase.html

1 million bar is 100 GPa. At these pressures
at room tempertures water will freeze, or
more accurately, crystallize into ice
modifications VII and, above 1 Mbar into ice X.

Liquid nitrogen cannot be produced by
compression of nitrogen at room temperatures,
its critical point is 126K = -147C.

Answer 2

Hello,

If you see the graphic here http://images.encarta.msn.com/xrefmedia/aencmed/targets/illus/cha/T073590A.gif, you may notice that liquid water remain in the same state even if the pressure is changing! But the boiling point would be considerably more than 100 degree

So

Answer 3

It would become a solid very very quickly!!!

Here's a link to water's phase diagram:

If you compress any liquid or gas to the extreme it will change phase. This is exactly how big chemical corporations like DuPont and Praxair create Liquid Nitrogen among others.

Answer 4

You will get one of the phases of ice, Ice X. It is symmetric and has a melting point between 1000K and 2400K.

Answer 5

It will turn into one of the more exotic phases of ice, like Ice X and Ice XI.

Answer 6

assuming you have no leaks and a container that will withstand the pressures, the water will hold the weight as it cannot be compressed.

Answer 7

By the way, I stole this from Alexander a while back.

Answer 8

Watter cannot be compressed.

Answer 9

You will get very high pressure water.

Answer 10

it will explode
