Newton's Law of Cooling says that the rate at which a body cools is proportional to the difference in temperature between the body and the environment around it. The temperature fit) of the body at time in hours after be environment having constant temperature To is ft) - Toce, where and k are constants.
A cup of coffee with temperature 155F is placed in a freezer with temperature 0°F. After 15 minutes, the temperature of the coffee is 46°F. Use Newton's Law of Cooling to find the coffee's temperature after 20 minutes.
After 20 minutes the coffee will have a temperature of DE
