Type: MCQ-numerical-Easy-Class 11
If the temperature of water in a calorimeter (T2) and hot water between double walls (T1) are measured at equal time intervals, which graph best represents ln(T2 - T1) versus time (t)?
A
A straight line with a negative slope
B
A straight line with a positive slope
C
A parabolic curve opening upwards
D
A horizontal line
Correct Answer
Option A
Detailed Explanation
The NCERT context suggests plotting ln(T2 - T1) versus time results in a linear relationship with a negative slope, indicating a decrease in the temperature difference over time.
