NEET Physics Newton's Law of Cooling Assertion Reason Question
Assertion (A): According to Newton's Law of Cooling, the rate of cooling of a body decreases as the temperature difference between the body and its surroundings decreases. | Reason (R): The rate of heat loss 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
From the NCERT context, Newton's Law of Cooling states that the rate of cooling is proportional to the excess temperature, which explains why the rate decreases as the temperature difference decreases.
