Mechanical model of kinetic theory
Mechanical model of kinetic theory

 

Code Number: 4D30.38

Demo Title: Kinetic Theory of Gases Demos - Ping Pong Balls

Condition: Excellent

Principle: Kinetic Theory of Gases

Area of Study: Thermodynamics

Equipment: 

Mechanical model of kinetic theory, Variac.

Procedure:

After each use the unit will have to be emptied and the cracked and broken balls replaced. Experimentation will help determine the optimum number of balls needed. Oil or grease the tightener pulley from time to time. The Variac may be turned all the way on without fear of harming the motor.
