Question

define coefficient of area expansion and write a relation for it​

Answer 1

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

Answer 2
