Question

5. The coefficient of thermal expansion depends on --------of the substance​

Answer 1

Answer:

Temperature

Thermal Expansion in Two Dimensions

For small temperature changes, the change in area ΔA is given by ΔA = 2αAΔT, where ΔA is the change in area A, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.

Answer 2

Answer:

linear expansion is the right answer
