The kinetic theory of gases is based on a number postulates from which the equation P= 1/3× N/V×m×µ² is derived (P is the pressure of the gas, N the number of molecules in the container, m the mass of each molecule and µ² is the mean square speed). State all the postulates and derive the conclusion that the average translational kinetic energy of a gas molecule is directly proportional to the absolute temperature from the given equation.

This may help but I don't think anyone at this site will do this for you. Most freshman texts have it.
