Description & Specifications
Kinetic Theory Model
Technical Specification
The motor is provided with a speed control.
Higher speeds give more extensive movements of the spheres.
Kinetic Theory Model provides in analogue form a visual representation of molecular movement in gases.
A piston, in a wide perspex tube, is vibrated by a low-voltage electric motor housed in a box supporting the tube.
Metal spheres, simulating gas molecules, are propelled upwards in a tube by the piston's vibrations.
For demonstrations to larger groups illumination from the side and a black background are recommended, to highlight the spheres.
The movements of the spheres are seen to be random both in direction and extent.
