NEET Physics Newton's Law of Cooling MCQ Question

Type: MCQ-conceptual-Easy-Class 11

According to Newton's Law of Cooling, which of the following correctly describes the rate of cooling of a body when its temperature is much higher than the surrounding medium?

A

The rate of cooling is directly proportional to the temperature difference between the body and surroundings.

B

The rate of cooling is inversely proportional to the temperature difference between the body and surroundings.

C

The rate of cooling is independent of the temperature difference between the body and surroundings.

D

The rate of cooling is constant regardless of temperature difference.

Correct Answer

Option A

Detailed Explanation

According to Newton's Law of Cooling, the rate of cooling is proportional to the excess temperature of the body over the surroundings, as given by the relation dQdt=k(TT1)\frac{dQ}{dt} = -k(T-T_1).
