Question

Increase in length per unit of the length, per degree celsius rise in temperature is called coefficient of linear expansion. Type 1 for true and 0 for false

Answer 1

Increase in length per unit of the length, per degree celsius rise in temperature is called coefficient of linear expansion.

$\alpha =\frac{△L}{L_o△T}$

where $△L$ is the amount of change in the length of the rod $L_o$ is the initial length of rod, $\alpha$ is the coefficient of linear expansion and $△T$ is the change in the temperature of the matter.

The SI unit of coefficient of linear expansion is $K^{-1}$
