To specify the microstate of the array after you finished this 0000075316 00000 n 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 is a real 4-step heat engine that has expansion and compression processes in which the engine will do useful mechanical work by lifting a 100-gram mass (and the piston) from one height to another. The mass is removed, and the air chamber is returned to the cold bath, closing the isobaric/isothermal cycle.
