On a hot day the freezers in a particular ice cream shop maintain an average tempature of Tc=-11 degree C while the tempature of the surroundings is Th= 29 degree C Randomized Varaibles -11, 29 Part (a) Calculate the maximum coefficient of performance COP for the freezers. Part (b) If the work input to the freezer is W = 2.95 kJ and the freezer actually removes Qc = 7.2 × 103 J from the ice cream each second, what is the real coefficient of performance? Part (c) An employee puts m = 1.05 kg of melted ice cream at T0 = 4.5° C into the freezer. Assuming that the ice cream freezes at T1 = -1.0° C, how long in seconds will it take for the ice cream to reach its freezing temperature? Take the specific heat capacity of the melted ice cream as c = 4,00
