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$4:3:2$
- DNone of these
✓
Answer
Correct option: A.
$1:2:3$
a
(a) As $\alpha = \frac{\beta }{2} = \frac{\gamma }{3}$ $\Rightarrow$ $\alpha :\beta :\gamma = 1:2:3$
(a) As $\alpha = \frac{\beta }{2} = \frac{\gamma }{3}$ $\Rightarrow$ $\alpha :\beta :\gamma = 1:2:3$
