Question

if coefficient of linear expansion of a metal is 1.2×10^5°C. Calculate the coefficient of superficial and cubical expansions. Please exlain the process.

Answer 1

Answer:

Relation between coefficient of linear expansion(\alphaα), coefficient of superficial expansion (\betaβ) and coefficient of cubical expansion (\gammaγ) is

\alpha:\beta :\gamma = 1:2:3 \\ \Rightarrow \gamma=\cfrac{3}{2} \betaα:β:γ=1:2:3⇒γ=23β

According to question; \gamma = x\beta \\ x=\cfrac{3}{2}γ=xβx=23
