A container of hot liquid is placed in a freezer that is kept at a constant temperature of 20F. The initial temperature of the liquid is 160F. After 5 minutes, the liquid's temperature is 60F. (a) Let y represent the temperature of the liquid in degrees Fahrenheit and let t represent the time in minutes after it is placed in the freezer. Write a differential equation %. (Use k for the constant of proportionality.) Ly: dt Find the general so y: Use the given initia (b) How much longer will it take for its temperature to decrease to 24F?
