Newton’s Law of Cooling:
Newton’s Law of Cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small.

According to Newton’s Law of Cooling, the rate of loss of heat from a body is directly proportional to the difference in the temperature of the body and its surroundings.

Newton’s Law of Cooling is given by,
