Question

what is the difference between linear expansion and coefficient of linear expansion​

Answer 1

Explanation:

Linear expansion means change in one dimension (length) as opposed to change in volume (volumetric expansion). ... The area thermal expansion coefficient relates the change in a material's area dimensions to a change in temperature. It is the fractional change in area per degree of temperature change.

Answer 2

Answer:

linear expansion is a phenomena which is increase in length due to increase in temperature.

while, coefficient of linear expansion is the constant of proportionality used to balance the the equation of linear expansion.
