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

A

`Cp-Cv` is larger for a diatomic ideal gas than for a monatomic ideal gas.

B

`Cp+Cv` is larger for a diatomic ideal gas than for a monatomic ideal gas.

C

`Cp//Cv` is larger for a diatomic ideal gas than for a monatomic ideal gas.

D

`Cp * Cv` is larger for a diatomic ideal gas than for a monatomic ideal gas.

Text Solution

Verified by Experts

The correct Answer is:
B, D
For monatomic gas,
`C_(v)=(3)/(2)R,C_(p)=(5)/(2)(R)`
For diatomic gas,
`C_(v)=(5)/(2)R,C_(p)=(7)/(5)R`
