Question
Consider the process on a system shown in figure. During the process, the work done by the system ______________ .
Options
continuously increases
continuously decreases
first increases then decreases
first decreases then increases

Solution
continuously increases
Work done by a system, `W=intPdV`
Here,
P = Pressure on the system
dV = change in volume.
Since dV is positive, i.e. the volume is continuously increasing, work done by the system also continuously increases.
