List the five principles of the Kinetic Molecular Theory. For each statement, answer this question: Do you think all gases follow this principle all of the time? Why or why not?
Give at least two examples of thermal expansion from real life. Describe what is happening to the particles in each case.
What are the three factors that influence the pressure of a gas? (number of particles, mass of particles, temperature of particles)
Explain what happens to the molecules of propane as they are pressurized in a propane tank.

http://www.chm.davidson.edu/vce/kineticmoleculartheory/basicconcepts.html Postulates 1. A gas consists of a collection of small particles traveling in straight-line motion and obeying Newton's Laws. 2. The molecules in a gas occupy no volume (that is, they are points). 3. Collisions between molecules are perfectly elastic (that is, no energy is gained or lost during the collision). 4. There are no attractive or repulsive forces between the molecules. 5. The average kinetic energy of a molecule is 3kT/2. (T is the absolute temperature and k is the Boltzmann constant.)
