NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
If the temperature difference between hot water in the calorimeter (T2) and the hot water between the double walls (T1) is such that a graph of ln(T2 - T1) versus time (t) yields a straight line, which of the following best describes the relationship between T2 and T1 over time?
A
T2 decreases logarithmically while T1 remains constant.
B
T2 and T1 both increase linearly with time.
C
T2 approaches T1 exponentially.
D
T2 and T1 both decrease exponentially with time.
Correct Answer
Option C
Detailed Explanation
The graph of ln(T2 - T1) versus time being a straight line indicates an exponential approach of T2 to T1, consistent with Newton's law of cooling.
