MCQ

Ratio among linear expansion coefficient $(\alpha)$, areal expansion coefficient $(\beta)$ and volume expansion coefficient $(\gamma)$ is

✓
$1: 2: 3$
B
$3: 2: 1$
C
$4: 3: 2$
D
None of these

✓

Answer

Correct option: A.

$1: 2: 3$

(a) As $\alpha=\frac{\beta}{2}=\frac{\gamma}{3} \Rightarrow \alpha: \beta: \gamma=1: 2: 3$
