Q2. Air, with a mass of 2 kg, undergoes a three-process cycle in a closed system as follows: 12: constant-pressure expansion 23: constant volume 31: constant-temperature compression The necessary information is T1 = 100C, T2 = 600C, and P1 = 200 kPa. = a) Sketch the cycle on a P-v diagram (4 marks) b) Find the net work done for the cycle. (9 marks) c) Determine the amount of heat transferred for the cycle
