The freezing point of any substance describes the point for the liquid to solid transition. The liquids can be super-cooled beyond their freezing points so that they don’t solidify until well below freezing point. The freezing point of water is 0 °C or 32 °F. The temperature may be lower if super-cooling occurs. shane stewart insuranceWebSince the liquid has less volume than the ice, lower pressure favors the ice. That raises the freezing point. Mike W. (published on 05/07/2011) Follow-Up #1: water freezing and pressure Q: This answer seems to be wrong. The freezing point of water doesn't go above 0C as pressure decreases (well OK, to 0.01C at 1/100th of an atmosphere). shane stikeleather
