NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a double-walled vessel containing hot water, where T1 is the temperature of the hot water between the double walls and T2 is the temperature of water in the calorimeter. A graph is plotted between ln(T2 - T1) and time (t). Which of the following best describes the process occurring in the system?
A
Newton's law of cooling
B
Thermal equilibrium being reached
C
Phase change at constant temperature
D
Linear thermal expansion
Correct Answer
Option A
Detailed Explanation
The graph between ln(T2 - T1) and time (t) suggests a process governed by Newton's law of cooling, where the rate of temperature change is proportional to the temperature difference.
