604. Why does Hot water cool more faster than Cold water?
The cooling rate of water or any other substance depends on the temperature difference between the object and the atmosphere. Greater the temperature difference, faster the rate of cooling. Well, to understand this better, take the case of two interconnected beakers, one with medium water level and the other with small water level. Water flows. But, if the water level is very high in the beaker, water flows even faster. This cooling phenomenon was discovered by Sir Isaac Newton, and is popularly known as Newton's law of cooling.
