A sample of gas expands from volume `V_(1)` to `V_(2)`. The amount of work done by the gas is greatest when the expansion is

adiabatic

isobaric

isothermal

equal in all above cases

Text Solution

Verified by Experts

The correct Answer is:

The P - V diagrams for the three processes is as shown in the figure.

For the same change in volume, the work done will be maximum for the curve having maximum area enclosed between the curve and the volume axis.
In this case `"Area"_("(isobaric)")gt"Area"_("(isothermal)")gt"Area"_("(adiabatic)")`
`therefore` The work done is maximum in an isobaric process.
