Problem $4-$ EnERGY Balance

A half$-$gallon container of milk at $65F$ is placed in a refrigerator. The milk cools to $40F$ 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 $0\mathrm{.}94Bt\frac{u}{l}b*R$

and $64l\frac{b}{f}{t}^3,$ respectively. Kinetic and potential energy effects can be neglected.
