NEET Physics Newton's Law of Cooling Assertion Reason Question
Assertion (A): The rate of cooling of a body decreases as the temperature of the body falls. | Reason (R): The rate of cooling is directly proportional to the temperature difference between the body and its surroundings.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that the rate of cooling is proportional to the excess temperature of the body over the surroundings, which decreases as the body cools down, thus decreasing the rate of cooling.
