Question

Use kinetic theory of gases to show that the average Kinetic energy of a molecule of an ideal gas is directly proportional to the absolute temperature of the gas.

Answer 1

Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.
