Heat TransferHard

Question

Cv and Cp denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then

Options

A.Cp - Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
B.Cp + Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
C.Cp / Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
D.Cp . Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.

Solution

For Monoatomic gas
Cv = R, Cp = R
For diatomic gas
Cp = R   Cp = R
