The initial state of a certain gas is (Pi , Vi , Ti ). It undergoes expansion till its volume becomes V_f . Consider the following two cases:

(a) The expansion takes place at constant temperature.

(b) The expansion takes place at constant pressure. Plot the P-V diagram for each case. In which of the two cases, is the work done by the gas more?

This is a short answer type question as classified in NCERT Exemplar

process 1 isochoric and process 2 is isothermal .

Since, work done = area under P-V curve . here area under the pV curve 1 is more . so work done is more when the gas expands in isochoric process.
