Since pressure and volume are inversely proportional to each other, there will be an increase in volume so the height will also increase which was observed from C to D. Inversely, there will be a decrease in height if there is an increase in pressure which happened from state A to B. This effect was observed as a rise in the object on the platform so is the piston height from state B to C.
