Which law states, “The rate of loss of heat by a body is directly proportional to the difference in temperature between the body and the surroundings.” (1) Doppler’s Effect (2) Newton’s law of cooling (3) Kirchhoff’s Law (4) Stefan’s Law
(2) Newton’s law of cooling Explanation: Kirchhoff’s Law – Kirchhoff’s Law signifies that good absorbers are good emitters. Stefan’s Law – The radiant energy emitted by a black body per unit area per unit time is directly proportional to the fourth power of its absolute temperature.
