NEET Physics Newton's Law of Cooling MCQ Question
Which of the following statements about Newton's Law of Cooling is correct?
The rate of cooling is proportional to the temperature difference between the body and its surroundings.
The cooling rate remains constant regardless of temperature difference.
The law applies only to surfaces that are not emitting heat radiation.
The rate of cooling increases as the temperature of the body approaches that of the surroundings.
Correct Answer
Detailed Explanation
According to Newton's Law of Cooling, the rate of cooling is indeed proportional to the excess temperature difference between the body and the surroundings, as stated in the NCERT context. This means that the greater the difference in temperature, the faster the rate of cooling.
