45. N Figure P21.45 shows a cyclic process ABCDA for 1.00 mol of an ideal gas. The gas is initially at P; = 1.50 × 105 Pa, V; = 1.00 X 10-3 m3 (point A in Fig. P21.45). a. What is the net work done on the gas during the cycle? b. What is the net amount of energy added by heat to this gas during the cycle? %D P(X105 Pa) B C 5.00 1.50 - A' D V (X10-3 m³) FIGURE P21.45 1.00 4.00
I need help solving number 11. In question 1, they say U=(3/2)PV I found work on the gas as -3/2PV, so therefore Q should be 6/2PV but the answer key says 6PV.
