Answer to Question #295209 in Physics for Dimple

Question

By how much will this area (in square decimeters) increase during a hot summer day on the month of May when the temperature is 120.20F?

Answer 1

To get the answer, we need to know the initial temperature T_i and the coefficient of linear expansion $\alpha$ of the material:

$$\Delta A=A_0\alpha^2(T_f-T_i)^2.$$
