In a certain cyclic engine (technically, a Carnot cycle), a perfect gas expands isothermally and reversibly, then adiabatically (q = 0) and reversibly. In the adiabatic expansion step the temperature falls. At the end of the expansion stage, the sample is compressed reversibly first isothermally and then adiabatically in such a way as to end up at the starting volume and temperature. Draw a graph of entropy against temperature for the entire cycle.
