There's a phase diagram for water
   at [1]https://ergodic.ugr.es/termo/lecciones/water1.html .
   I don't know this stuff well, really.  It looks like as pressure rises
   above 10^8 Pa ice undergoes successive solid phase transitions.
   I'm not sure yet how to relate volume, pressure, and temperature
   together for a solid.
