A diatomic ideal gas (y = 1.4) undergoes a thermodynamic cycle involving an isobaric contraction, followed by an isothermic expansion and lastly an adiabatic contraction. This would act as a heat pump that uses work to extract heat from one area and move it to another (e.g. a refrigerator). The PV diagram for this cycle is shown in the image below. PA The isobaric process occurs at a pressure of 160400 Pa. The isothermic expansion increases the volume of the gas from 5.44 x 10 2 m3 to 9.63 x 10-2 m3. What is the net work done on the gas?The coefficient of performance for a heat pump is defined as K It is a measure of how effective the pump is at extracting heat (Qin ), as compared to the amount of work needed to extract the heat ( W ). What is the coefficient of performance for this heat pump
