The coefficient of linear expansion of a solid depends on the unit of ___.

Solution

The coefficient of Linear Expansion is the increase in the length of an object per unit length per degree rise in temperature. Let $l_{1}$ and $l_{2}$ be the length of a solid at $t_{1}$ and $t_{2}$ temperatures respectively. Then $α = \frac{l_{2} - l_{1}}{l_{1} (t_{2} - t_{1})}$ , $α = c o e f f i c i e n t o f l i n e a r e x p a n s i o n$ Since it is the ratio of length, its unit does not depend on length. It only depends on temperature.
