Question

Ratio among linear expansion coefficient (α), areal expansion coefficient (β) and volume expansion coefficient (γ) is

• A. 1 : 2 : 3
• B. 3 : 2 : 1
• C. 4 : 3 : 2
• D. None of these

Answer 1

Answer: (A)

1 : 2 : 3

Answer 2

As $\alpha = \frac{\beta}{2} = \frac{\gamma}{3}$ ⇒ $\alpha:\beta:\gamma = 1:2:3$
