At ordinary temperatures, the molecules ...

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 higher temperatures, molar specific heat capacity at constant volume, `C_(V)` is

A

`C_(V)=(3)/(2)R` for a monotomic gas

B

`C_(V)gt(3)/(2)R` for a monoatomic gas

C

`C_(V)lt(5)/(2)R` for diatomic gas

D

`C_(V)gt(5)/(2)R` for a diatomic gas
