Newton's Law of Cooling

Newton's Law of Cooling states that the rate at which an object loses heat is directly proportional to the temperature difference between the object and its surroundings. In simpler terms, a hot object cools faster when it's much warmer than the environment, but slows down as it approaches room temperature. The larger the temperature gap, the quicker the cooling; as the object cools down, the rate decreases. This principle explains everyday phenomena like a hot cup of coffee cooling or a heated metal object returning to room temperature over time.
