What about conservation of energy? 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. sure you. If the temperature is kept constant (isothermal), the pressure will be allowed to change.
