6.2.1

Describe the kinetic theory in terms of the movement of particles whose average energy is proportional to temperature in Kelvin’s.

The kinetic theory states that when temperature of a substance is increased the average kinetic energy of the particles increases too. However if the temperature reaches absolute zero it means there is no average kinetic energy as there is no motion of particles.

In the apparatus shown below, the increase in voltage mimics the rise in temperature while the height of the polystyrene cylinders represents the increase in volume.
