Question

State and prove the Newton's Law of Cooling.​

Answer 1

Explanation:

A body initially at a temperature T1 cools by Convection and radiation in a room where the temperature is T0 . The body obeys of Newton's Law of cooling which can be written as. dQ/dt=hA(T−T0) where A is the area of the body and h is a constant called the surface coefficient of heat transfer.

Answer 2

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

➣ For small temperature difference between a body and its surrounding, the rate of cooling of the body is directly proportional to the temperature difference and the surface area exposed. dQ/dt ∝ (q – qs)], where q and qs are temperature corresponding to object and surroundings.
