Rate of Cooling
The rate of cooling refers to how quickly an object loses heat to its environment. When a hot object is placed in a cooler surrounding, it cools down faster initially, and the cooling rate decreases over time. This phenomenon can be explained by Newton's Law of Cooling, which states that the rate of heat loss is proportional to the temperature difference between the object and its surroundings. In practical terms, this means that a hot cup of coffee cools rapidly at first, then slows down as it approaches room temperature.
