An ideal gas undergoes a thermodynamic cycle consisting of three processes:
Process 1-2: Isothermal compression from P1 = 1.0 bar, V1 = 1.6 m3 to V2 = 0.20 m3
Process 2-3: Constant pressure process to a volume V3 = V1
Process 3-1: Constant volume process, U1 - U3 = -3549 kJ.
There are no significant changes in kinetic or potential energy. Determine the heat transfer and work for each of the processes. What is the internal energy change for Process 1-2? What is the internal energy change for Process 2-3?
