NEET Physics Thermal Expansion MCQ Question
Type: MCQ-numerical-Medium-Class 11
Density of substance at 0°C is 10 gm/cc and at 100°C, its density is 9.7 gm/cc. The coefficient of linear expansion of the substance will be
A
10²
B
10⁻²
C
10⁻³
D
10⁻⁴
Correct Answer
Option C
Detailed Explanation
The volume expansion is related to linear expansion by β = 3α. Given the density change, solving gives α = 10⁻³.
