expansion area 1AArea thermal expansion (also known as aerial thermal expansion) happens when any change in temperature expands the area.

Area Thermal Expansion Formulas

\(\large{ \Delta A  =   A_f \;-\;  A_i  }\)                      

\(\large{ \Delta A  =  2 \alpha A_i \Delta T }\)       


\(\large{ \Delta A }\) = area thermal expansion

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

\(\large{ A_f }\) = final area of object

\(\large{ A_i }\) = initial area of object

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