C(p) and C(v) denote the molar specific ...

`C_(p)` and `C_(v)` denote the molar specific heat capacities of a gas at constant pressure and volume 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

Text Solution

Verified by Experts

The correct Answer is:
B, D
`C_(P) - C_(V) = R` Always constant
`(C_(P))/(C_(V)) = gamma` decreases with atomicity
`(C_(P) + C_(V)) "and" C_(P),C_(V)` depends on degree of freedom therefore it will be more for diatomic gas
