Q. At ordinary temperature, the molecules of an ideal gas have only translational and rotational kinetic energies. At high temperature they may also have vibrational energy as a result of this at high temperature

Kinetic Theory

Solution:

$C _{ V }=\frac{ fR }{2},$ degree of freedom for diatomic gas and polyatomic gas at room temperature is $f$ but at higher temperature their degree of freedom increases by one due to vibrational motion of molecule
