A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes in series, beginning at state 1 where p1 = 1 bar, V₁ = 1.5 m3, as follows: Process 1-2: Compression with pV = constant, W12 = -104 kJ, U₁ = 512 kJ, U2 = 690 kJ Process 2-3: W23 = 0, Q23 = -150 kJ Process 3-1: W31 = +50 kJ There are no changes in kinetic or potential energy. Determine: (a) Sketch the process on P-V diagram. (b) Q12, Q31, and U3, each in kJ. (c) The net work of the cycle, in kJ, (d) Can this cycle be a power cycle? Explain.
