Why is water incompressible?
In: 1
Liquid water forms a lot of hydrogen bonds with each other. Due to the shape of the water molecules, you can’t really squeeze the molecules any closer together without snapping these hydrogen bonds, which takes a lot of pressure to do so.
However, with enough pressure, you can indeed snap those bonds and force water into a denser configuration. However, since water is already pretty dense to begin with, even this ‘denser configuration’ isn’t that much denser than what you started with. Eventually it becomes so dense that it solidifies, although not into the normal type of ice that we know (which is actually less dense than liquid water)
If you look at a phase diagram of water, you’ll see that compressing it at room temperature (~300K) will eventually turn it into Ice VI, then Ice VII, then Ice X, then Ice XI
