NEET 2013 Physics Thermal Expansion MCQ Question
Type: MCQ-numerical-Medium-Class 11
The density of water at 20°C is 998 kg/m³ and at 40°C is 992 kg/m³. The coefficient of volume expansion of water is:
A
3 × 10⁻⁴/°C
B
2 × 10⁻⁴/°C
C
6 × 10⁻⁴/°C
D
10⁻⁴/°C
Correct Answer
Option B
Detailed Explanation
The coefficient of volume expansion is calculated using the formula ΔV/V = βΔT. Using the given densities, β is found to be 2 × 10⁻⁴/°C.
