The phase diagram for water shows that at very high pressure and room temperature water becomes ice. Is it possible to this confirmed this by experiment?

  • $\begingroup$ Are you asking has it been confirmed by experiment (yes, yes it has...) or how to design your own experiment to do that? $\endgroup$ – paisanco Sep 19 '16 at 1:48
  • $\begingroup$ Yes, water does become ice at room temperature and very high pressure, but for this discussion, "very high pressure" means greater than 950 MPa, or 9400 atmospheres, or 137800 psi. www1.lsbu.ac.uk/water/water_phase_diagram.html $\endgroup$ – pr1268 Sep 19 '16 at 3:20
  • $\begingroup$ My interest is how do you design an experiment to confirm the presence of ice under these severe conditions $\endgroup$ – Bob Sep 19 '16 at 11:10
