Which of the following statements about Newton's Law of Cooling is correct?

A

The rate of cooling is proportional to the temperature difference between the body and its surroundings.

B

The cooling rate remains constant regardless of temperature difference.

C

The law applies only to surfaces that are not emitting heat radiation.

D

The rate of cooling increases as the temperature of the body approaches that of the surroundings.

Correct Answer
