In an isobaric process, heat is supplied to a monoatomic ideal gas. The fraction of heat that goes itno mechanical work is

A

1

B

`2/3`

C

`3/5`

D

`2/5`

Text Solution

Verified by Experts

The correct Answer is:
D
`Q_(P)=nC_(P)DeltaT=5/2nRDeltaT`
`W=PDeltaV=nRDeltaT`
`impliesW/(Q_(P))=(nRDeltaT)/(5/2nRDeltaT)=2/5`
