Question

what is newton's law of cooling??? ​

Answer 1

Newton's law of cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).

Newton's Law of Cooling Formula. Sir Isaac Newton created a formula to calculate the temperature of an object as it loses heat. The heat moves from the object to its surroundings. The rate of the temperature change is proportional to the temperature difference between the object and its surroundings.

One of the limitations of Newton's law of cooling is that this law holds true only if the temperature of the surroundings remains constant throughout the cooling if the body. It is not valid for large difference between body and it's surrounding

Answer 2

Answer:

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.

Definition: 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, dT/dt = k(Tt – Ts)

Where,

Tt = temperature at time t and

Ts = temperature of the surrounding,

k = Positive constant that depends on the area and nature of the surface of the body under consideration.
