Required information
The PV diagram shown is for a heat engine that uses 1.370 mol of a diatomic ideal gas as its working substance. In the
constant-temperature processes A and C, the gas is in contact with reservoirs at temperatures 373 K and 273 K,
respectively. In constant-volume process B, the gas temperature decreases as heat flows into the cold reservoir. In
constant-volume process D, the gas temperature increases as heat flows from the hot reservoir.
