Thermodynamic Processes

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

Show answer and solution

Answer: (d)

Work done = area under the $P$ - $V$ curve between $V_1$ and $V_2$ .
Starting from the same state, the isobaric line stays highest, then the isothermal curve, and the adiabatic curve falls fastest.
$W_{isobaric} > W_{isothermal} > W_{adiabatic}$
So the answer is (d) isobaric.
