A sample of gas expands from volume V1 to V2. The amount of work done by the gas is greatest, when the expansion is
-
- adiabatic
- isobaric
- isothermal
- equal in all cases
Correct Option: B
In thermodynamics for same change in volume, the work done is maximum in isobaric process because in P – V graph, area enclosed by curve and volume axis is maximum in isobaric process.
So, the choice (b) is correct.
