The well-insulated container shown in Fig. P8-l03E is initially evacuated. The supply line contains air that is maintained at 200 psia and 100°F. The valve is opened until the pressure in the container is the same as the pressure in the supply line. Determine the minimum temperature in the container when the valve is closed.
