I6-36. Molecular Motion Demo - Avogadro's Hypothesis
To help justify Avogadro's hypothesis using a model.
E.M.E. Molecular Motion Demonstrator with accessories as pictured.
A set of small balls of varying mass models the air. The balls are set into motion by vibration of the walls. Using two sets of six balls with differing mass, start the device in motion. Both sets of balls move around and occupy the entire space. The small balls move faster than the large balls, so they "occupy" the same amount of space overall. This seems like a hokie argument, but if it helps,......
