This Kinetic Gas Theory Vibration Apparatus demonstrates the motion and behavior of molecules in gases. A small electric motor running at 4-12V DC vibrates a platform inside a transparent tube, causing many small steel balls to vibrate violently. Increasing vibration violence simulates increased gas temperature, and increasing the weight of the float simulates increased gas pressure. Supplied with steel balls and 2 floats. CE approved. Suitable for physics classrooms studying the kinetic theory of gases and gas laws.
