Product Description

This 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. Tiny metal spheres, simulating gas molecules, are propelled upwards in a tube by the piston’s vibrations. The movements of the spheres are seen to be random both in direction and extent. The motor is provided with a speed control. Higher speeds give more extensive movements of the spheres. The electric motor requires a 6V DC power supply capable of providing a current of 2.5A. For demonstrations to larger groups illumination from the side and a black background are recommended, to highlight the spheres.
