title: Kinetic Theory Apparatus
aka: Cenco kinetic theory apparatus

  A clear cylinder has a movable piston and a vibrating bottom plate.   Beads inside the cylinder model the behavior of atoms/molecules as the emperature increases.

computer simulation can be found on Phet.

   Why does the piston rise when the beads move faster?
    How do the beads produce pressure?
