Aclosed, rigid tank contains a two-phase liquid–vapor mixture of refrigerant 22 initially at -20oc with a quality of 50.36%. energy transfer by heat into the tank occurs until the refrigerant is at a final pressure of 6bar. determine the final temperature, in oc. if the final state is in the superheated vapor region, at what temperature, in oc, does the tank contain only saturated vapor?
