A 0.2 m^3 rigid tank initially contains refrigerant 134a at 1 MPa, saturated vapor. The tank is connected to a supply line that contains refrigerant 134a at 1.2 MPa, 30 degrees C. Refrigerant is allowed to enter the tank until the tank contains saturated liquid at 1.2 MPa Determine:
a. the mass of refrigerant that has entered the tank (kg)
b. the final temperature in the tank (degrees C)
c. the amount of heat transfer (kJ).
