Definition of Expansivity:
The amount a material expands or contracts per unit length due to a one-degree change in temperature.
Fractional increase in the length (linear expansivity), area (superficial expansivity), or volume (volume expansivity) of a solid, per degree to its corresponding value at a standard temperature. Also called coefficient of expansion.
