Professor Modyn is filling a poorly insulated tank. Superheated steam is flowing through a supply line at 2500 kPa and 435 °C. A valve connects the supply line to the tank, which has a volume of 1.000 m³. Initially, the valve is closed and the tank contains a saturated liquid-vapor mixture of water with a pressure of 225 kPa and a quality of 50.2%. The valve is opened and the steam is allowed to flow into the tank until a saturated vapor at 4000 kPa is obtained. At this point the valve is closed. Find the mass entering the tank and the heat interaction. Note: The IUPAC sign convention for heat is used. Heat into the system has a positive value. mass entering the tank: kg heat interaction: kJ
