Question
A gas expands from volume V1 to V2. In which case work done will be more: isothermal expansion, isobaric expansion or adiabatic compression?
Solution
The indicator diagram (i.e., P-V curve) for an isothermal, isobaric and adiabatic process is as shown below.
Work done by the gas is represented by the area under the P-V graph.
Thus, from the above graph, work done by the gas during isobaric expansion is maximum and adiabatic expansion is minimum.
