Water under high pressure

  1. Mar 13, 2009 #1
    Hi there,

    I was wondering what happens when a great pressure is applied to water. I think that applying pressure to water vapor would turn it into water (liquid) since it has a higher density. So at first I thought that water would turn into ice, but quickly I realised that would be odd since ice has a lower density.
    So my question is, what happens to the volume, the temperature and the phase of the H2O when you apply a big pressure to it?

    Depending on the constraints, you'll probably end up with superheated liquid that has a reduced volume. I think the big factor would be what the heat transfer during the compresion was.

    Thanks, that makes sense :) !
