A monatomic gas expands at constant pressure on heating. The percentage of heat supplied that increases the internal energy of the gas and that is involed in the expansion is

Options

A. `75%,25%`
B. `25%,75%`
C. `60%,40%`
D. `40%,60%`

Answer

C

Explanation

`(DeltaU)/(DeltaQ)=(1)/(gamma)=(1)/((5)/(3))=0.6` i.e., `60%`
`(DeltaW)/(DeltaQ)=100-60=40%`
