It makes me wonder what the pressure dependence is for this phase change. http://www1.lsbu.ac.uk/water/water_phase_diagram.html http://www1.lsbu.ac.uk/water/water_phase_diagram.html
Pressures inside a particular piece of cellular machinery can be much higher than 0.1 MPa (1 bar).
- marcosdumay 10y agoThere's nothing on the article about thermal expansion and heat coefficient. So I'm assuming in both states they are the same. If so, there is really no reason to expect this state change to be much affected by pressure. There also seems to be no latent heat absorbing¹, and from the widely varying changing temperature, I imagine both states coexist on those ~20°C. Water is really weird. 1 - Otherwise people would have discovered this long ago.
