1 2 3 2 2 points 1kg of air at 1.02 bar, 20C is compressed reversibly according to the law pv1.3= constant, to a pressure

1 2 3 2 2 points 1kg of air at 1.02 bar, 20C is compressed reversibly according to the law pv1.3= constant, to a pressure of 5.5bar and temperature of 432.7K. Calculate the work done (kJ kg-) on the air during the compression. w = 133.46 kJ kg 1 w = -133.46 kJ kg-1 w = 233.46 kJ kg- w = -233.46 kJ kg-1 w = 4133.46 kJ kg-1 4 -D
