Physics-Thermal Expansion
NEET Physics Thermal Expansion MCQ Question
Type: MCQ-numerical-Hard-Class 11
A metallic cube has a side length of 10 cm at 20°C. If the coefficient of linear expansion of the metal is 1.5 x 10^-5 °C^-1, what will be the change in volume of the cube when it is heated to 80°C?
A
5 cm^3
B
0 cm^3
C
5 cm^3
D
6.0 cm^3
Correct Answer
Option A
Detailed Explanation
The volume expansion is given by ΔV = 3α_lVΔT. With α_l = 1.5 x 10^-5 °C^-1 and ΔT = 60°C, ΔV = 3 x 1.5 x 10^-5 x (10^3) x 60 = 4.5 cm^3.
