A gas undergoes a cycle in a piston–cylinder assembly consisting of the following three processes: P

A gas undergoes a cycle in a piston–cylinder assembly consisting of the following three processes:

Process 1–2: Constant pressure, p = 1.4 bar, V1 = 0.028 m3W12 = 10 kJ
Process 2–3: Compression with pV = constantU3 = U2
Process 3–1: Constant volume, U1 - U3 = -20 kJ

There are no significant changes in kinetic or potential energy.

(a) Calculate the net work for the cycle, in kJ.
(b) Calculate the heat transfer for process 1–2, in kJ.
