State Newton's law of cooling and draw the graph showing cooling of hot water with temperature.

Explanation

Newton’s law of cooling. The rate of cooling (or rate of loss of heat) of a body is directly
proportional to the temperature difference between the body and its surroundings,
provided the temperature difference is small.
The rate at which a body loses heat by radiation depends on
(i) The temperature of the body
(ii) The temperature of the surrounding medium
(iii) The nature and extent of the exposed surface
