NEET Physics Newton's Law of Cooling MCQ Question
Consider a graph where the y-axis represents the temperature difference (ΔT = T2 - T1) and the x-axis represents time (t), depicting the cooling of a hot object. Which of the following statements is correct regarding the initial rate of cooling as observed in the graph?
The initial rate of cooling is higher due to a larger temperature difference.
The rate of cooling remains constant throughout the process.
The initial rate of cooling is slower due to low thermal conductivity.
The rate of cooling is independent of the temperature difference.
Correct Answer
Detailed Explanation
The initial rate of cooling is higher because the rate of heat loss is proportional to the temperature difference between the object and its surroundings, as mentioned in the NCERT context about Newton's Law of Cooling.
