At the end of this activity, students should be able to define a phase and a phase change, describe and analyze cooling and heating curves, explain phase changes in terms of the kinetic theory, define melting and boiling points, describe melting and freezing processes in terms of dynamic equilibrium, explain the process of vaporization and the existence of vapor pressure, tell the difference between vaporization and boiling, explain why boiling point depends on external pressure as well as describe sublimation and deposition.
