NEET Physics (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
If the logarithm of the temperature difference ln(T2 - T1) is plotted against time t for a system involving hot water in a calorimeter and hot water in a double-walled vessel, what does the slope of the resulting line represent?
A
Rate of heat loss from the system.
B
Time constant of the cooling process.
C
Initial temperature difference.
D
Final equilibrium temperature.
Correct Answer
Option B
Detailed Explanation
The slope of the line in a plot of ln(T2 - T1) vs. time represents the time constant of the cooling process, as it relates to the exponential decay of the temperature difference.
