# Volumetric Thermal Expansion

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Volumetric thermal expansion, abbreviated as $$\Delta V$$, 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

$$\large{ \Delta V = V_f - V_i }$$

$$\large{ \Delta V = 3 \; \alpha \; V_i \; \Delta T }$$

Where:

$$\large{ \Delta V }$$ = volumetric thermal expansion

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

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

$$\large{ V_f }$$ = final volume

$$\large{ V_i }$$ = initial volume
