Volume thermal expansion coefficient

Description

Thermal expansion is the tendency of matter to change in volume in response to a change in temperature through heat transfer. For a solid, we can ignore the effects of pressure on the material, and the volumetric thermal expansion coefficient is the fractional change in area per degree of temperature change. (The volume of a material changes by some fixed fractional amount).
