Question

give a relation for superficial expansion​

Answer 1

Area or superficial Expansion: Superficial expansion is defined as the increase in surface area of the solid on heating. If you consider at 00C area of a solid is A0 then its area at t0c is given by: A0(l+βt). Unit of β is 0C-1 or K-1. Where β is known as the coefficient of superficial expansion. 6α = 3β = 2γ

Answer 2

Answer:

the increase in surface are of the solid on heating
