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

    A) 3         

    B)                    2.5  

    C) 1.5       

    D)        2

    Correct Answer: C

    Solution :

    [c] \[3\,k=x.\,2\,k\] [Here \[\alpha \] is coefficient of linear expansion so coefficient of cubical expansion\[=3\alpha \] & coefficient of superfacial expansion\[=2\alpha \]] \[x=\frac{3}{2}=1.5\]
