How does lower pressure affect freezing point
WebThe freezing point is a certain temperature range of a substance at which both liquid and solid substances will be at equilibrium. At this phase, their vapour pressure will be equal. If you add a non-volatile solid to the volatile liquid, the combination of solvents will have less vapour pressure. First, let us learn about the freezing point. WebSince 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).
