Question

what is coefficient of linear expansion.


​

Answer 1

Answer:

The coefficient of linear expansion may be defined as the increase in length per unit length when the temperature is raised 1°C.

Answer 2

The coefficient of linear expansion may be defined as the increase in length per unit length when the temperature is raised 1°C.

Expansion means, change or increase in length. If the change in length is along one dimension (length) over the volume, then it is called linear expansion. ... \alpha _{L} is the coefficient of linear expansion. dL is the unit change in length. dT is the unit change in temperature.
