11. A heat engine takes 0.350 mol of an ideal diatomic gas around the cycle shown in the pV diagram of. Process 12 is at constant volume, process 23 is adiabatic, and process 31 is at a constant pressure of 1.00 atm. The value of y for this gas is 1.40. The magnitude of the change in internal energy for each process is |AU1A2|=2150L IAUbs | =780], and I AU361|=1400L I) \\ 3 1 \\l. T1: 300K T3 = 492K v Find the pressure and volume at points 1, 2, and 3. a b. Find the net work done by the gas in the cycle. c Find the net heat ow into the engine in one cycle. d . What is the thermal efficiency of the engine? How does this efficiency compare with that of a Carnot-cycle engine operating between the same minimum and maximum temperatures T1 and T2
