Question

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

• A. cannot be infered from the given data
• B. isobaric
• C. adiabatic
• D. equal in all casses

Answer 1

The correct option is B isobaric

The work done in a process is the area under a PV graph
If we observe three PV graphs for each process, we can see that there is a larger area enclosed under the isobaric graph.
