A fixed tank contains refrigerant R-134a and has a volume of 5000 mL. Initially the tank holds refrigerant at 500kPa and 40°C. The tank is connected to a supply line of R-134a that has refrigerant at 1600kPa and 60°C. A valve is opened between the tank and the supply line and the tank is filled until the pressure reaches 1200kPa and 50 oC. How much heat (in kJ) has been added to, or removed from, the tank during this process? MUST use Energy balance equation solve and state all assumptions made
