Task id12002
Figure 8.4 shows a diagram of a cycle carried out with 0.2 mol of a monatomic ideal gas. Sections BC and DA are adiabatic. Calculate the efficiency of a heat engine operating in this cycle. Determine the work done by the gas on section BC. Find the maximum efficiency value of a heat engine using a heater and a refrigerator with which this cycle was carried out, if at point B the gas was in thermal equilibrium with the heater, and at point D - in thermal equilibrium with the refrigerator.
