volumetric Thermal Expansion Coefficient

Volumetric thermal expansion coefficient ( $$\beta$$ ) (also known as coefficient of volumetric thermal expansion) is the ratio of the change in size of a material to its change in temperature.

Volumetric Thermal Expansion Coefficient FORMULA

$$\large{ \beta = \frac { 1 }{ V } \frac {\Delta A } {\Delta T} }$$

Where:

$$\large{ \beta }$$   (Greek symbol beta) = volumetric thermal expansion coefficient

$$\large{ V }$$ = volume of the object

$$\large{ \Delta V }$$ = area differential

$$\large{ \Delta T }$$ = temperature differential
