What is the cubical coefficient of thermal expansion for metals?

Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.


What is the scientific name for the inrease in the size of a substance when the temperature is increased?

Thermal Expansion. Each liquid or pure solid has a specific thermal of expansion. The thermal expansion of a substance is not linear, though for most of the temperatures we encounter in normal life, it is close enough to linear to be able to use a linear definition called the "Coefficient of Thermal Expansion".
