The kinetic energy of gas molecules or atoms is: (3/2)kTN/M where k is Boltzman constant, T is absolute temperature, N is avogadros number and M is molecular weight. The formula is derived from http://en.wikipedia.org/wiki/Kinetic_theory.
Assume that the gas is steam with M = 18 kg/mol at 373K, it is equivalent to approximately 260 J/kg but suppose i cool the steam up to 40C based on Cdt + Lf (C is specific heat, dt is change in temperature and Lf is latent heat of vaporization), it becomes an overunity of 10420 more effective. From what assumption or derivation I am wrong? or if I'm right where does the excess energy came from?
