Answer 2

Given that,

Coefficient of linear expansion in solid​.

We know that,

Linear expansion :

Linear expansion is equal to the change in length divided by original length and change in temperature.

In mathematically,

$\dfrac{\Delta L}{L}=\alpha \Delta T$

$\alpha=\dfrac{\Delta L}{L\Delta T}$

Here, $\Delta L$ = change in length

L = original length

$\Delta T$ = change in temperature

$\alpha$ = coefficient of linear expansion

Hence, The coefficient of linear expansion in solid​ is $\dfrac{\Delta L}{L\Delta T}$
