Thermal expansion

Question

Coefficient of apparent expansion of same liquid in glass vessel is ‘G’ and in silver vessel is ‘S’. If coefficient of linear expansion of glass is ‘A’, coefficient of linear expansion of silver is

Moderate

A

$\frac{G + A - S}{3}$
B

$\frac{G - 3 A + S}{3}$
C

$\frac{G + 3 A - S}{3}$
D

$\frac{S + 3 A + G}{3}$

Solution

$\begin{array}{l} γ_{r} is Same \\ {(γ_{a} + γ_{g})}_{1} = {(γ_{a} + γ_{g})}_{2} \end{array}$
