STANDARD Physics Thermal Expansion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The coefficient of volume expansion of liquid is γ. The fractional change in its density for ΔT rise in temperature is
A
γΔT
B
ΔT/γ
C
1 + γΔT
D
1 − γΔT
Correct Answer
Option A
Detailed Explanation
The fractional change in density is given by the negative of the coefficient of volume expansion times the change in temperature, hence γΔT.
