Mechanical Model of a Gas: Collisions in 2 and 3 Dimensions. The Apparatus is a simple mechanical model to represent gas molecules in a cylinder colliding with a moveable piston with increasing energy as the gas is heated. Model of a Gas: Electric Motor vibrates the steel balls. Piston changes the volume. Note: On request this can be done with different sized balls. Same set-up as C+10+5 and C+55+10
