Answer:

According to kinetic theory of gases, the pressure .P. exerted by one mole of an ideal gas is

P=

ρC2 where ρ is density of the gas.

∴P=

C2⇒PV=

MC2

But PV=RT for one mole of ideal gas.

mC2∝T

But, 1/2 mC^(2)` is average translational kinetic energy per molecule of a gas.

Therefore, average kinetic energy of molecule of an ideal gas is directly proportion to the absolute temperature of the gas.
