Degree of freedom equation
By the equipartition theorem, internal energy per mole of gas equals cv T, where T is absolute temperature and the specific heat at constant volume is cv = (f)(R/2). R = 8.314 J/(K mol) is the universal gas constant, and "f" is the number of thermodynamic (quadratic) degrees of freedom, counting the number of ways in which energy can occur.
