Vedclass · Answer

(B) Hydrogen $(H_2)$ is a diatomic molecule.At very high temperatures,the vibrational degrees of freedom become active.The total degrees of freedom $(f)$ for a diatomic molecule at high temperature include:$3$ translational degrees of freedom,$2$ rotational degrees of freedom,and$2$ vibrational degrees of freedom.Total degrees of freedom $f = 3 + 2 + 2 = 7$.The fraction of energy associated with rotational motion is given by the ratio of rotational degrees of freedom to the total degrees of freedom.Fraction $= \frac{f_{rot}}{f_{total}} = \frac{2}{7}$.

If hydrogen gas is heated to a very high temperature,then the fraction of energy possessed by gas molecules corresponding to rotational motion is ...........
