States of Matter


Chapter Objectives
At the end of this unit students will be able to
1.  describe the assumpitons of the kinetic molecular theory as it applies to gases.
2.  interpret gas pressure in temrs of kinetic theory.
3.  define the relationship between Kelvin temperature and average kinetic energy.
4.  identify factors that determint physical properties of a liquid.
5.  define evaporation in terms of kinetic energy.
6.  describe the equilibrium between a liquid and its vapor.
7.  identify the conditions at which boiling occurs.
8.  evaluate how the way particles are organized explains the properties of solids.
9.  identify the factors that determine the shape of a crystal.
