A heat engine takes 0.350 mol of an ideal diatomic gas around the cycle shown in the pV diagram of (Figure 1). Process 1 2 is at constant volume, process 2 +3 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 AU1-al = 2180 J. JAU:-al = 785 J. and AUs1l = 1396 J. Part A Find the pressure at points 1, 2, and 3.
