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 temperature

Options

A. `C_(v)=3R//2` for monatomic gas
B. `C_(v) gt 3R//2` for monatomic gas
C. `C_(v) lt 5R//2` for diatomic gas
D. `C_(v) gt 5R//2` for diatomic gas

Explanation

`C_(v)=(f)/(2)R`, where `f` is the degree of freedom
