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 heat is transferred to or from the gas as it goes from B to C to A?
