Coefficient of thermal expansion

The coefficient of thermal expansion is used in two ways:

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

• as a volumetric thermal expansion coefficient
• as a linear thermal expansion coefficient

These characteristics are closely related. The volumetric thermal expansion coefficient can be measured for all substances of condensed matter (liquids and solid state). The linear thermal expansion can only be measured in the solid state and is common in engineering applications.
