Question

if coefficient of cubical expansion is x times coefficient of superficial expansion then the value of x is​

Answer 1

Answer:

Explanation:

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

3 /γ  = 2/β

Thus γ=  3/2  β

​But γ=xβ (Given in question)

so , x = 3/2 = 1.5
