Question

The coefficient of area expansion of a solid is

Answer 1

The area thermal expansion coefficient relates the change in a material's areadimensions to a change in temperature. It is defined as αA=1AdAdT α A = 1 A dA dT 

Answer 2

Answer:The area thermal expansion coefficient relates the change in a material's area dimensions to a change in temperature. It is defined as αA=1AdAdT α A = 1 A dA dT .

Explanation:

relationship between the area and linear thermal expansion coefficient is given as the following: αA=2αL α A = 2 α L .
