NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
In an experiment, the temperature difference between hot water in a calorimeter (T2) and the surrounding hot water (T1) is measured over time. If the graph of ln(T2 - T1) versus time is a straight line, what does this indicate about the cooling process?
A
The cooling follows Newton's Law of Cooling.
B
The cooling rate is constant over time.
C
The heat transfer is purely conductive.
D
The system is in thermal equilibrium.
Correct Answer
Option A
Detailed Explanation
The linear graph of ln(T2 - T1) versus time suggests an exponential decrease in temperature difference, characteristic of Newton's Law of Cooling.
