Law of Equipartition of Energy
For any system in thermal equilibrium, the total energy is equally distributed among its various degrees of freedom. The energy associated with each molecule of the system per degree of freedom of the system is (1/2)kT. where , and T = absolute temperature of the system.
If the system possesses degree of freedom f, then
