SUMMARY

Compressing water leads to a phase transition where, under sufficient pressure, water molecules are forced into a solid state, forming various types of ice (such as ice VI and VII) depending on the temperature and pressure conditions. The phase diagram of water is crucial for understanding these transitions, as it illustrates the relationship between temperature and pressure. Experiments simulating these extreme conditions are feasible in laboratory settings, allowing for the study of water's behavior under high pressure.

PREREQUISITES
  • Understanding of phase diagrams, specifically water's phase diagram.
  • Knowledge of molecular structures and types of ice (e.g., ice VI, ice VII).
  • Familiarity with experimental techniques for generating high pressure in laboratory settings.
  • Basic principles of thermodynamics related to phase transitions.
NEXT STEPS
  • Research the phase diagram of water and its implications for phase transitions.
  • Study the properties and structures of different types of ice, particularly ice VI and VII.
  • Explore laboratory methods for achieving high pressures, such as diamond anvil cells.
  • Investigate the thermodynamic principles governing phase changes in substances.
USEFUL FOR

Scientists, researchers in materials science, and anyone interested in the physical properties of water and its behavior under extreme conditions.

what happens to the atoms in water when it is compressed so much that all atoms have no space to move?

im guessing that it will become thicker, almost soup like.

But what happens after that, does it become solid water?

also, is it possible to set up such an experiment in the real world that can simulate these types of massive pressures it would take to achieve this?

Thanks

Yes, eventually it will turn to solid (assuming your temperature doesn't change).

Find your temperature / pressure on this phase diagram [1] then track upwards as you increase the pressure at constant temperature. It will eventually turn to ice as the molecules are forced together, though the pressure at which this occurs depends on the temperature.

[1] http://en.wikipedia.org/wiki/Phase_diagram#Crystal_phase_diagrams

You'll notice that there are many different types of ice (VI, VII, etc), each of which has a slightly different crystal structure. Depending on your temperature and pressure, the ice you form by compression will have one of these structures.

And yes, it's possible to set this up in experiment (huge pressures can be achieved in labs!).
 
That pretty much answered all of my burning questions.

Much appreciated
Thanks
