One mole of a monatomic ideal gas, in the initial state T = 273 K, P = 1 atm, is subjected to the following three processes, each of which is conducted reversibly: a. A doubling of its volume at constant pressure, b. Then a doubling of its pressure at constant volume, c. Then a return to the initial state along the path P = 6.643 104V2 + 0.6667. Calculate the heat and work effects which occur during each of the three processes.
