A rigid container of 0.03m3 contains refrigerant 134a at 1MPa and of 100% quality. This container is connected by means of a valve with a supply line that conducts the refrigerant 134a at 1.6Mpa and 36oC. then the valve is opened and the refrigerant is allowed to enter the container containing saturated liquid at 1.6MPa the valve is closed. Determine: a) the mass of the refrigerant that entered the container and b) the amount of heat transferred.
