A half-gallon container of milk at 65o F is placed in a refrigerator. The milk cools to 40o F after 25 minutes have elapsed. If energy is removed from the milk by heat transfer at a constant rate, determine the rate of heat transfer, in Btu/s, during the cooling process. The specific heat and density of the milk are 0.94 Btu/lb∙o R and 64 lb/ft3 , respectively. Kinetic and potential energy effects can be neglected.
