Question

Quizplus · Accepted Answer

According to Newton's Law of Cooling, the rate of cooling is proportional to the temperature difference between the body and its surroundings. As the body cools, this temperature difference decreases, leading to a slower rate of cooling. Therefore, it will take more than 10 minutes to cool from 70°C to 60°C.
