Question

What is the realtion between linear expansion,volume expansion,superficial expansion.
​

Answer 1

Answer:

α= β/2= γ/3

(where α= linear expansion, γ = volume expansion, β= superficial expansion.)

hope it helps. mark me as the brainliest

Answer 2

Answer:

Relation Between α and β:

Let l, b and A be the length, breadth, and area of the plate at temperature t °C. Consider superficial expansion of the plate area. Thus the coefficient of superficial expansion is twice the coefficient of linear expansion
