An air-conditioning system is to be filled from a rigid container that initially contains 5 kg of liquid r-134a at 24°c. the valve connecting this container to the air-conditioning system is now opened until the mass in the container is 0.265 kg, at which time the valve is closed. during this time, only liquid r-134a flows from the container. presuming that the process is isothermal while the valve is open, determine the final quality of the r-134a in the container and the total heat transfer.
