Question

If coefficient of cubical expansion is x times
coefficient of superficial expansion, then the
value of x is

​

Answer 1

Coefficient of cubical expansion (γ) is related to coefficient of superficial expansion (β) as given below

3γ = 2β

Thus γ = 23 β

But γ=xβ (Given in question)

⇒x= 23

. =1.5.
