! Required information Problem 07.025 - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Refrigerant-134a enters the coils of the evaporator of a refrigeration system as a saturated liquid-vapor mixture at a pressure of 140 kPa. The refrigerant absorbs 200 kJ of heat from the cooled space, which is maintained at -10°C, and leaves as saturated vapor at the same pressure. Problem 07.025.a - Entropy change of the refrigerant in an evaporating process Determine the entropy change of the refrigerant. Use the tables for R-134a. (You must provide an answer before moving on to the next part.) The entropy change of the refrigerant is KJ/K.
