Vacuum or Pressure Apparatus

The Kinetic Theory Model apparatus is used along with the vibration generator to demonstrate the movement of molecules in a gas. An approximate relationship between the floating height, i.e., volume of the gas and weight of the disc, i.e., pressure of the gas can be observed. The platform has a rubber surface and small stainless steel balls are loaded into the tube. With the change in the speed of vibration generator, the heating of the gas stimulates resulting change in the agitation of the balls inside the tube. It comprises theory of piston, steel balls and a base or placing on an overhead projector.
