A gas expands isothermally from state A to state B, in the process absorbing 35 J of heat. It’s then compressed isobarically to state C, where its volume equals that of state A. During the compression. 22 J of work are done on the gas. The gas is then heated at constant volume until it returns to state A. (a) Draw a pV diagram for this process, (b) How much work is done on or by the gas during the complete cycle? (c) How much
