A quantity of 1.0 mol of an ideal monatomic gas is taken through a complete cycle in three steps: (1→2) increase in pressure at constant volume, (2→3) adiabatic expansion and (3→1) decrease in volume at constant pressure. Temperature and pressure values are given below.
T1 = 300 K T2 = 600 K T3 = 455 K P1 = 1 atm = 1 x 105 Pa
