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). Different materials expand by different amounts. Just how much a particular material expands depends on the forces of cohesion between neighboring atoms or molecules The linear thermal expansion - the change in length - of an object can be expressed as. dl = L 0 α (t 1 - t 0) (1) where . dl = change in object length (m, inches) L 0 = initial length of object (m, inches) α = linear expansion coefficient (m/m o C, in/in o F) t 0 = initial temperature (o C, o F) t 1 = final temperature (o C, o F) Coefficient of Linear Expansion is the rate of change of unit length per unit degree change in.
