Consider the following pressure-volume graphs. Which of these graphs represents expansion? the behavior of a gas undergoing isochoric reduction of pressure then isobaric P P A B V P V P 4 C D V VA thermodynamic system undergoes the three processes shown in the diagram (A - B, B-C, and C - A). PA = 1.4 x 105 Pa, PB = 7.5 x 105 Pa, VA = 0.02 m3, Vc = 0.10 ma. How much work, in Joules, is done by the system? Please round your answer to the nearest whole number (integer).
