A piston-cylinder assembly initially has 100 kPa pressure and 2 Liter air at 25 ° C. The air is then compressed to 620 kPa pressure and 160 ° C. Useful work for compression is 1.22 kJ. Assuming that the ambient pressure and temperature are 100 kPa and 25 ° C respectively,

a) Calculate the availability of air in the initial and final states,

b) the minimum work required for the compression process,

c) Calculate the second law efficiency of the state change.
