Question

The superficial expansity (Expansivity lis 1/x times the cubic expansivity. The value of x is
a)2/3
b) 3/2
c)2
d)3

Answer 1

Answer:

the value of x is 3/2

Explanation:

As we know the relation between linear expansion, superficial expansion and volume expansion is given as

$\alpha : \beta : \gamma = 1 : 2 : 3$

so we can say that

$\beta = 2\alpha$

$\gamma = 3\alpha$

now from above equations

$\frac{\beta}{\gamma} = \frac{2}{3}$

so the superficial expansity is 2/3 times the cubic expansity

so the value of x is 3/2
