Question: A 0 . 5 - m 3 rigid tank contains air initially at 1 0 0 0 kPa and 2 2 C . Air at

A 0.5-m3 rigid tank contains air initially at 1000 kPa and 22C. Air at 2000 kPa and 22C is slowly added until the pressure reaches 1500 kPa. Assume that the temperature in the tank does not change and that specific heats vary with temperature. How much heat was removed, in kJ, to maintain the temperature
