equipartition law मीनिंग इन हिंदी

After Planck identified that Wien's law can be extended to all frequencies, even very low ones, by interpolating with the classical equipartition law for radiation, physicists wanted to understand the quantum behavior of other systems.
A diatomic molecule like H 2 can rotate about either of the two axes perpendicular to the one joining the two atoms, and as the equipartition law of statistical mechanics demands that the available thermal energy be divided equally among the degrees of freedom, for such a gas in thermal equilibrium 3 / 5 of the energy can go into unidirectional motion, and 2 / 5 into rotation ( actually, the vibration of the molecule should not be neglected, see gas heat capacity ).
