Rate of cooling depends on the A)Temperature difference between the body and the surroundings B)Nature of the radiating surface C)Area of the radiating surface D)All of these
Option D) Newton’s Law of Cooling states that the rate of temperature of the body is proportional to the difference between the temperature of the body and that of the surrounding medium. When a body cools by radiation, then rate of cooling depends upon the following factors: l Nature of the radiating surface, that is, emissivity; l Area of the radiating surface; l Mass of the radiating surface; l Specific heat of the radiating body; l Temperature of radiating body and l Temperature of the surrounding.
