Agas within a piston–cylinder assembly undergoes a thermodynamic cycle consisting of three processes: process 1–2: constant volume, v = 0.024 m^3 process 2–3: expansion with pv = constant. process 3–1: constant pressure, p = 1.8 bar, w3-1 = -8 kj. there are no significant changes in kinetic or potential energy. calculate the net work for the cycle, in kj.
