13.7. Applying Newton's Law of Cooling

Newton's law of cooling says that the rate of temperature change of an object is proportional to the temperature difference of that object from the environment:

In this equation, T is the temperature of an object, t is time, k is a constant, and Te is the temperature of the environment.
