QUESTION:

In a heat engine, 2.00 mol of a diatomic gas are taken through the cycle ABCA, as shown in Figure 19-20. (The diagram is not drawn to scale.) At A the pressure and temperature are 5.00 atm and 600 K. The volume at B is twice the volume at A. The segment BC is an adiabatic expansion, and the segment CA is an isothermal compression. (a) What is the volume of the gas at A? (b) What are the volume and temperature of the gas at B? (c) What is the temperature of the gas at C? (d) What is the volume of the gas at C? (e) How much work is done by the gas in each of the three segments of the cycle? ( f ) How much heat is absorbed or released by the gas in each segment of this cycle?
