One kg of R-134a contained within a piston-cylinder assembly undergoes a process from a state where the temperature is T1 = 20◦C and the refrigerant is a saturated liquid to a state where the pressure is p2 = 10 bar and the quality is x2 = 50%. Determine the change in specific entropy of the refrigerant, in kJ/kg·K. Can this process be accomplished adiabatically?
