A group of students were tasked to compare the coefficient of performance of the freezer after observing how effective it operates after it converts a certain amount of water to ice in 6 hours. They were able to construct the table shown below. Compute the actual and ideal COP for both freezers Panasonic White Westinghouse 0.08 hp Power rating 42 W Mass of water 15 kg 20.5 kg Latent heat of solidification 80 cal/g 80 cal/g Interior temperature Exterior temperature 0.9- - 10°C 31'C 20°C

! 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.
