$$C_v$$ and $$C_p$$ denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then

A

$$C_p - C_v$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas

B

$$C_p + C_v$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas

C

$$C_p / C_v$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas

D

$$C_p . C_v$$ is larger for a diatomic ideal gas than for a monoatomic ideal gas
