Question

what is the relation between linear, superficial and volume expansion​

Answer 1

Explanation:

Thus the coefficient of superficial expansion is twice the coefficient of linear expansion. Relation Between α and γ: Consider a thin rectangular parallelopiped solid of length, breadth, height, and volume l0, b0, h0, and V0 at temperature 0 °C. Let the solid be heated to some higher temperature say t °C.
