saturated mixture of refrigerant R-134a is contained in a frictionless piston-cylinder device. The initial temperaure of the mixture is 39.37 oC. Over an hour 400 kJ of thermal energy is transferred to the roon which is maintained at a constant temperature of 22 oC. The condensation process is internally reversible. Determine the total entropy generation during this thermal energy process. Give your answer to three significant digits in kJ/K.
