Answer:
Consequently, the coefficient of linear expansion is expressed as the per degree Celsius, or change in the length of a 1 unit long material when there is a 10 C rise in temperature. Coefficient of Linear Expansion Formula. As per the definition, the formula is expressed as. αL1 = ∆L / ∆T, or.

The coefficient of linear expansion is the change in length of a specimen one unit long when its temperature is changed by one degree (see linear expansion). ... A metal such as lead which has a low melting point and is relatively easily compressed, expands a great deal for a given rise in temperature.
