Volumetric thermal expansion (also known as volume thermal expansion) takes place in gasses and liquids when a change in temperature, volume or type of substance occures.

Volumetric Thermal Expansion Formulas

\(\large{ \Delta V  =   V_f \;-\;  V_i  }\)                      

\(\large{ \Delta V  =  3 \alpha \Delta T V }\)        

\(\large{ \Delta V  = V \left( 1 + 3 \alpha \Delta T \right) }\)

\(\large{ \Delta V  =  \beta   V_i  \Delta T }\)         

\(\large{ \frac { \Delta V}  { V_i }  =  \beta   \Delta T }\)

Where:

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

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

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

\(\large{ V }\) = volume

\(\large{ V_f }\) = final volume of object

\(\large{ V_i }\) = initial volume of object

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