A 40-ft3 adiabatic container is initially evacuated. The supply line contains air that is maintained at 150 psia and 90°F. The valve is opened until the pressure in the container is the same as the pressure in the supply line. Determin the work potential of the air in this container when it is filled. Take T0 = 80°F.
