Volumetric thermal expansion, abbreviated as \(\Delta V\), also called volume thermal expansion or linear volume thermal expansion, takes place in gasses and liquids when a change in temperature, volume or type of substance occures.


Volumetric thermal expansion Formulas

\(\large{ \Delta V  =  V_f - V_i  }\)   
\(\large{ \Delta V  =  3 \; \overrightarrow{\alpha_l} \; V_i  \; \Delta T  }\)  


 Units English Metric
\(\large{ \Delta V }\) = volumetric thermal expansion \(\large{ \frac{in^3}{in^3\;F} }\) \(\large{ \frac{mm^3}{mm^3\;C} }\)
\(\large{ \overrightarrow{\alpha_l} }\)   (Greek symbol alpha) = linear thermal expansion coefficient \(\large{ \frac{in}{in\;F} }\) \(\large{ \frac{mm}{mm\;C} }\)
\(\large{ \Delta T }\) = temperature change \(\large{F}\) \(\large{C}\)
\(\large{ V_f }\) = final volume \(\large{in^3}\) \(\large{mm^3}\)
\(\large{ V_i }\) = initial volume \(\large{in^3}\) \(\large{mm^3}\)
