Kinetic Theory Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-PLE-10302
Quick Answer: The Kinetic Theory Apparatus models gas behaviour with small spheres bouncing on a rubber diaphragm inside a transparent plastic tube. A DC motor drives a piston under the diaphragm to keep the spheres in motion.

Key Features
Transparent cylindrical plastic tube, closed at the top by a cap with holes.
Rubber diaphragm across the lower end of the tube.
Piston below the diaphragm, driven by a DC motor.
Metal spheres of 1/8 inch diameter stand in for gas molecules.
Holding ring with three equally spaced tightening screws grips the tube firmly.
Mounted on a base with two 4 mm socket terminals for the motor supply.

About This Product
Once the motor runs, the agitated diaphragm throws the spheres about at random, much as kinetic theory pictures the molecules of a gas. The same set-up can be used to show associated effects, such as air becoming thinner with increasing altitude.
Frequently Asked Questions
What drives the spheres inside the tube?
A piston below the rubber diaphragm is connected to a DC motor. When the motor runs, the piston agitates the diaphragm and sets the 1/8 inch metal spheres moving.
How is the motor connected?
The base carries two 4 mm socket terminals for the electrical connection to the motor.
What can the apparatus demonstrate?
It demonstrates the kinetic theory of gases and associated phenomena such as the thinning of air with increasing altitude.
