`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 then for a monatomic ideal gas

B

`C_p + C_v` is larger for a diatomic ideal gas than for a monatomic ideal gas

C

`C_P//C_v` is larger for a diatomic ideal gas than for a monatomic ideal gas

D

`C_p C_v` 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 `and For diatomic gas, `C_V = 5/2 R, C_p = 7/5 R`.
