The above equation (PV=const) can not be applied. For what process is it valid? What process is the problem about?

Perhaps you could do it in a couple of steps?

The graph B shows the V-T plot for a mass m at a constant pressure P. What would be the V-T plot for one quarter of that mass, m/4, at the same constant pressure P?

Finally, what would now be the plot for m/4 at half the pressure, viz., P/2?
