Question

Define Linear Expansion! ​

Answer 1

Answer:

Linear expansion means change in one dimension (length) as opposed to change in volume (volumetric expansion). To a first approximation, the change in length measurements of an object due to thermal expansion is related to temperature change by a coefficient of linear thermal expansion

Answer 2

Linear expansion is basically the increase in length of a material in relation to the increase of the temperature of the material.

The coefficient of linear expansion is a guiding numerical expression, which is generally different for different materials. To indicate the increase in length of the material for every degree increase in temperature.
