tank initially contains air at 300 kPa , 300 K . Air slowly escapes from the tank until the pressure drops to 100 kPa . The air that remains in the tank undergoes a process described by
pv^(1.2)=
constant. For a control volume enclosing the tank, determine the heat transfer, in kJ. Assume ideal gas behaviour with constant specific heats. Dont copy other answers in chegg. Use transient system analysis
