Equipartition Principle
Energy per degree of freedom is:
Select the correct option:
Solution
(1/2) k T
The Law of Equipartition of Energy states that for a system in thermal equilibrium at temperature T, the total energy is distributed equally among all its degrees of freedom.
- The average energy associated with each degree of freedom is 21kBT.
- For a molecule with f degrees of freedom, the total average internal energy per molecule is 2fkBT.
