The equipartition theorem relates the temperature of a system with the systems energies. Equipartition is in equilibrium; all the energy is shared among all of its forms. It gives a total average kinetic and potential energies for a system at a given temperature for which the heat capacity can be computed. Equipartition will depict the average value of individual components of the energy. Equipartition theorem makes good predictions in certain conditions, however it becomes inaccurate when quantum effects must be considered. Quantum effects must be considered at low temperatures.
