What is the definition of cubic Expansivity?

CUBIC EXPANSIVITY OF A LIQUID : the real (or absolute) cubic expansivity of a liquid is defined as the increase in volume per unit volume per unit rise in temperature.

What is area of Expansivity?

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.

What is linear expansivity of a material?

The constant is called the linear expansivity of the metal, given the symbol a (which is why I kept writing out "is proportional to"!). Definition: The linear expansivity of a substance is the fractional change in length of a sample of the substance per degree C change in temperature.
