Question

State True or False:

The coefficient of linear expansion is three times the coefficient of volume expansion.

• A. True
• B. False

Answer 1

The correct option is B

False

$\alpha \to \text{Coefficient of linear expansion}\beta \to \text{Coefficient of surface expansion}\gamma \to \text{Coefficient of volume expansion}$
We know that,
$\alpha =\frac{\beta }{2}=\frac{\gamma }{3}$
So, $\alpha =\frac{1}{3}rd$ times of $\gamma$
