NEET Physics Newton's Law of Cooling MCQ Question
Consider a graph depicting the cooling of a hot body over time, where the y-axis represents the temperature difference and the x-axis represents time . According to Newton's Law of Cooling, which statement best describes the initial rate of cooling?

The initial rate of cooling is higher when the temperature difference is greater.
The initial rate of cooling remains constant irrespective of .
The initial rate of cooling is lower when the temperature difference is greater.
The initial rate of cooling depends solely on the ambient temperature.
Correct Answer
Detailed Explanation
Newton's Law of Cooling states that the rate of cooling is proportional to the temperature difference between the body and its surroundings. Initially, when is greater, the rate of cooling is higher.
