  1. Phase Changes Courtesy www.lab-initio.com

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

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

  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, Tc = 374°C and 218 atm).
