Suppose 67.5 moles of an ideal monatomic gas undergo the series of processes shown in Figure. (a) Calculate the temperature at the points A, B, and C. (b) For each process, A → B, B →C, and C → A, state whether heat enters or leaves the system. Explain in each case. (c) Calculate the heat exchanged with the gas during each of the three processes.
