According to the kinetic theory of gases...

According to the kinetic theory of gases, the pressure of a gas is expressed as `P = ( 1)/( 3) rho bar(c )^(2)` where `rho` is the density of the gas, `bar(c )^(2)` is the mean square speed of gas molecules. Using this relation show that the mean kinetic energy of a gas molecule is directly proportional to its absolute temperature.
