A heat engine takes 0.350 mol of an ideal diatomic gas around the cycle shown in the pl/ diagram of (Figure 1). Process 1 -> 2 is at constant volume, process 2 -> 3 is adiabatic, and process 3 -> 1 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-+2) = 2180 J, |AU2 +3| = 785 J, and |4U3 +1) = 1396 J. Figure
