NEET Physics Newton's Law of Cooling Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

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.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D
