A gas undergoes the following three-step cycle:
• 1→2: isochoric pressure increase from P1=200kPa, V1=0.010m3 to P2=400kPa.
• 2→3: isobaric expansion at 400kPa to a volume V3=0.030m3.
• 3→1: return to the initial state along a straight-line segment on the P–V diagram.
Calculate the net work done ON the gas during one complete cycle.
