A monoatomic gas is supplied heat Q very slowly keeping the pressure constant. The work done by the gas is

`(2)/(3)Q`

`(3)/(5)Q`

`(2)/(5)Q`

`(1)/(5)Q`

Text Solution

Verified by Experts

The correct Answer is:

`DeltaQ=DeltaU+DeltaW`
`=nC_VDeltaT+nRDeltaT`
`=n.(3R)/(2).DeltaT+nRDeltaT`
`Q=(5nRDeltaT)/(2)`
`nRDeltaT=(2Q)/(5)=DeltaW`
