Please help with question G

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 14U3 +1| = 1396 J. Figure 2 . T7 = 600 K 1.00 atm T = 300 K T3 = 492 K O - VPart D Calculate W for each of the three processes. Express your answers in joules to three significant figures, separated by commas. W1 +2, W2 +3, W3 +1 = 0,785,-559 J Submit Previous Answers Correct V Part E Find the net work done by the gas in the cycle. Express your answer with the appropriate units. W = 226 J Submit Previous Answers V Correct Part F Find the net heat flow into the engine in one cycle. Express your answer in joules to three significant figures.
