Chapter 22, Problem 17A

Does Newton’s law of cooling apply to warming as well as to cooling?

To determine

To Explain: Newton’s law of cooling applies to warming as well as to cooling.

Explanation of Solution

Introduction:

The heat loss is directly proportional to the change in temperature between the two entities.

As per Newton’s law of cooling the rate of change in temperature of an object is directly related to the difference between its temperature. Its applicable for the bodies of all temperatures i.e. a hot body and a cold body. And so, the rate at which a body gets heated is equal to the rate at which it cools.

Conclusion:

Hence, Newton’s law applies to both warming and cooling.
