Temperature

The temperature of a system is the measure of the average

kinetic energy of the particles of the system.

Average K.E of the system = Total K.E of all particles

number of particles

• We assume that energies of all particles are equal

Temperature = K.E of one particle

But in fact, the K.E of each particle differs from 1 particle to

another in the same substance
