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.
1 \(C_{V} < \dfrac{3 R}{2}\), monoatomic
2 \(C_{V}=\dfrac{3 R}{2}\), monoatomic
3 \(C_{V} < \dfrac{5 R}{2}\), diatomic
4 \(C_{V}=\dfrac{5 R}{2}\), diatomic
Explanation:
\(C_{V}=\dfrac{f R}{2}\), 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 for diatomic gas and more then one for polyatomic gas. but there is no effect of by on degree of freedom of ideal gas or monoatomic gas. A \(f = 3\) for monoatomic gas. \(\therefore {C_V} = \frac{3}{2}R\)

The value of molar specific heat at constant pressure for one mole of triatomic gas (triangular arrangement) at temperature \(T\,K\) is \((R=\) universal gas constant)
1 \(\dfrac{2}{7} R\)
2 \(3 R\)
3 \(4 R\)
4 \(\dfrac{5}{2} R\)
Explanation:
Here, the degrees of freedom \(F=6\), \(C_{P}=\left(1+\dfrac{F}{2}\right) R=\left(1+\dfrac{6}{2}\right) R=4 R\)
