Question

The coefficient of linear expansion of a solid depends upon

• A. the unit of pressure
• B. the nature of the material only
• C. the nature of the material and temperature
• D. unit of mass

Answer 1

Answer: (B)

the nature of the material only

Answer 2

$\text { Linear expansion }=\text { fractional change in length }=\frac{\Delta L }{ L }=\alpha \Delta T$ Coefficient of linear expansion is a characteristic property of material. It is constant for specific material and different for different material.
