Q. The coefficient of volumetric expansion of lamina is $5 \times$ $1 0^{- 5} /^{\circ} C$ . Its coefficient of linear expansion will be:

$1.6 \times 1 0^{- 5} /^{\circ} C$

$1.1 \times 1 0^{5} /^{\circ} C$

$2 \times 1 0^{- 6} /^{\circ} C$

$3 \times 10/^{\circ} C$

$α = \frac{γ}{3}$
$= \frac{5 \times 1 0 ^{- 5}}{3}$
$= 1.6 \times 1 0^{- 5} /^{\circ} C$

Q. The coefficient of volumetric expansion of lamina is 5× 10−5/∘C. Its coefficient of linear expansion will be:
