6.2.1. I can describe kinetic theory

Temperature in Kelvins is proportional to the average kinetic energy of the particles in a substance. 

Particles in a substance move randomly as a result of the kinetic theory they possess. Because of the random nature of these movements and collisions, not all particles in a substance have the same value of kinetic energy. The average of these values is taken and is related directly to its absolute temperature. 

Increasing temperature therefore means an increase in the average kinetic energy of the particles of a substance. As a substance is supplied with extra energy through heating it, the average kinetic energy of the particles as well as the temperature is raised. 

Using the kinetic theory apparatus we were able to see how particles, represented by the ball bearings, move randomly as a result of the kinetic theory they possess. To increase the voltage would be like increasing the temperature of the substance, this resulted in an evident increase in the average kinetic energy of the ball bearings.
