Volumetric Thermal Expansion Coefficient

Written by Jerry Ratzlaff on . Posted in Thermodynamics

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

\(\large{ \alpha_v  =  \frac { 1 }{ V }  \frac {\Delta V } {\Delta T}   }\)         

Where:

\(\large{ \alpha_v }\)   (Greek symbol alpha) = volumetric thermal expansion coefficient

\(\large{ \Delta V }\) = volume differential

\(\large{ \Delta T }\) = temperature differential

\(\large{ V }\) = volume of the object
