State Newton`s law of cooling.

Text Solution

Verified by Experts

Newton`s Law of cooling states that the rate of loss of heat of a body is directly proportional to the difference in temperature between the body and its surrounding porvided the difference in temperatures is small and the nature of the radiating surface remains same.
`-(dQ)/(dt)prop (T-T_(s)) or -(dQ)/(dt)=K(T-T_(s))`
Where k is the proportionality constant
