The mechanical and thermodynamic work is also measured and calculated in the process. 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. 0000047286 00000 n
