Question

how is superficial expansion different from volume expansion?

Answer 1

Volume Expansion: Volume expansion is defined as the increase in the volume of the solid on heating. With a change in temperature ∆t the change in volume of a solid is given by ∆v=Vy∆t where the coefficient of volume expansion is y. ... Unit of β is 0C-1 or K-1. Where β is known as the coefficient of superficial expansion.
