Newton’s Law of Cooling Definition
Newton was the first to study the relationship between the heat lost by a body to its surrounding. He states that the more difference in the temperature between the object and its surrounding the more heat is radiated by the body.
Newton’s Law of Cooling states that
“The rate of heat loss from a body is directly proportional to the difference in temperature between the body and its surroundings, given that the temperature difference is not large.”
This law is used to explain, why hot water or milk left on a table cools faster than a little warm milk or water left on the table. Newton’s law of cooling helps us to teel the temperature of anybody without actually measuring it, given the initial temperature of the body and the temperature of the surrounding.
Newton’s Law of Cooling
Newton’s Law of Cooling is the fundamental law that describes the rate of heat transfer by a body to its surrounding through radiation. This law state that the rate at which the body radiate heats is directly proportional to the difference in the temperature of the body from its surrounding, given that the difference in temperature is low. i.e. the higher the difference between the temperature of the body and its surrounding the more heat is lost and the lower the temperature the less heat is lost. Newton’s Law of Cooling is a special case of Stefan-Boltzmann’s Law.
