ID Code: I6-34
Purpose: Model gas pressure.
Description: Two sets of small balls (larger green and smaller blue) are used to model the molecules in the air. The balls are set into motion by vibration of the walls. Increasing the vibration speed of the walls imparts more energy to the balls, simulating higher temperature.

Using a single set of balls, the distribution of velocities can be observed. Using two sets of balls with different mass, the average velocity of the smaller balls is seen to be greater than that of the larger balls.
