Question

Do state law of equipartition of energy .use this law to calculate specific heats of monoatomi diatomic triatomic gases​

Answer 1

According to the law of equipartition of energy, the energy is equally distributed among all the degrees of freedom and that is equal to 1/2 kT. Therefore, if the degrees of freedom of gas molecules are f then internal energy of 1 mole of gas will be
, where N is the Avogadro number.
