At ordinary temperatures, the molecules of an ideal gas have only translational and rotational kinetic energies. At high temperatures they may also have vibrational energy. As a result of this at high temperature: (`MA to ` Monoatomic gas & `DA to ` Diatomic gas)

A

`C_v = (3R)/(2)` for a MA gas

B

`C_v gt (3R)/(2) ` for a MA gas

C

`C_v lt (5R)/(2)` for a DA gas

D

`C_v gt (5R)/(2)` for a DA gas
