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. 160 150 A 140 D 373 K 130 120 B 110 100 273 K 90 80 0.019 0.02 0.021 0.022 0.023 0.024 0.025 0.026 Volume (m³) What is the net work done for the cycle?

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of en…
