Task 20819.
A monoatomic ideal gas in the amount of 0.1 kmol, having a volume V1 = 5 m3 at a pressure of P1 = 105 Pa, was compressed isobarically to a volume of V2 = 1 m3, then compressed adiabatically, and finally expanded at a constant temperature to the initial pressure and volume. Construct a schedule for the process. Find: temperature, pressure and volume for characteristic points of the cycle; heat Q1 obtained from the heater; heat Q2, given to the refrigerator; work A, completed by gas per cycle; Efficiency of the cycle.
