Refrigerant 134a, initially (state 1) a saturated liquid at -80C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. The change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature. If the mass of the refrigerant is 0.1 kg, determine (a) heat transfer using first law of thermodynamics in kJ...
