WebFeb 3, 2024 · Derivation of Newton’s Law of Cooling from Stefan’s Law: Let us consider a body whose surface area is A having absolute temperature T and kept in the surrounding having absolute temperature T o . Let e be the emissivity (or coefficient of emission) of the surface of the body. Let (T -T o) = x, where x is Small. ∴ T = T o + x. WebNewton's Law of Cooling states that the temperature of a body changes at a rate proportional to the difference in temperature between its own temperature and the temperature of its surroundings.
