# $\;C_{p}\;$ and $\;C_{v}\;$ denote the molar specific heat capacities of a gas at constant pressure and constant volume respectively . Then
(a) $\;C_{p}-C_{v}\;$ is larger for a diatomic gas than for a monoatomic gas.(b) $\;C_{p}+C_{v}\;$ is larger for a diatomic gas than a monoatomic gas.(c) $\;\large\frac{C_{p}}{C_{v}}\;$ is larger for a diatomic gas than for a monoatomic gas.(d) $\;C_{p}\;.C_{v}\;$ is larger for a diatomic gas than for a monoatomic gas.
