When heat Q is supplied to a diatomic gas of rigid molecules, at constant volume its temperature increases by `triangleT` the heat required to produce the same change in temperature, at a constant pressure is

A

`2/3 Q`

B

`5/3 Q`

C

`3/2 Q`

D

`7/5 Q`

Text Solution

Verified by Experts

The correct Answer is:
D
`Q=n((5R)/(2)) triangleT`
Q' (at constant pressure)= `nC_ptriangleT= nxx(7R)/(2)triangleT implies Q' (7Q)/(5)`.
