Question: The well-insulated container shown in Fig. P7-98E is initially evacuated. The supply line contains air that is maintained at 150 psia and 140F. The valve

The well-insulated container shown in Fig. P7-98E is initially evacuated. The supply line contains air that is maintained at 150 psia and 140°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.
