Aclosed system contains 1.2 kg of air, initially at 250 oc and 900kpa. the system first undergoes a polytropic process (polytropic exponent, n=1.25) to a pressure of 600 kpa, followed by a constant pressureprocess to a temperature of 250 oc and then, finally, an isothermalprocess that returns it to its initial state thus completing a cycle. determine the a)volume of the system (air) at all the statesb)boundary work for each process c)net work (sum of all individual work components) of the cycled)show the processes on a p vs vdiagram
