2 CA Standards Students know energy is released when a material condenses or freezes and is absorbed when a material evaporates or melts.Students know energy is released when a material condenses or freezes and is absorbed when a material evaporates or melts.

3 Water phase changes Temperature remains __________ during a phase change. constant

4 Effect of Pressure on Boiling Point

5 Phase Diagram  Represents phases as a function of temperature and pressure.  Critical temperature: temperature above which the vapor can not be liquefied.  Critical pressure: pressure required to liquefy AT the critical temperature.  Critical point: critical temperature and pressure (for water, T c = 374°C and 218 atm).
