Question

The unit of the coefficient of linear expansion it

Answer 1

hey mate here is your answer ✌♥✌♥

the unit of coefficient of linear expansion is..

Alpha
$\alpha$
also....

$\alpha = 2 \beta = 3 \gamma$
where

alpha is coefficient of linear expansion

beta is coefficient of areal expansion

and gamma is coefficient of volume expansion

and the formula for change in length is
$l2 - l1 = l1 \alpha (t2 - t1)$
