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

Area Thermal Expansion Formulas

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

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

\(\large{ \Delta A  = A_i \left( 1 + 2 \alpha \Delta T \right) }\)

\(\large{ \Delta A  =  \gamma   A_i  \Delta T }\)         

\(\large{  \frac  { \Delta A } { A_i }    =  \gamma   \Delta T }\)

Where:

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

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

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

\(\large{ \Delta A }\) = area differential

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

\(\large{ \gamma }\)   (Greek symbol gamma) = area thermal expansion coefficient
