Q. The real coefficient of volume expansion of glycerine is $0.000597\ per℃$ and linear coefficient of expansion of glass is $0.000009\ per℃$. Then the apparent volume coefficient of expansion of glycerine is
A) $0.000558\ per℃$
B) $0.00057\ per℃$
C) $0.00027\ per℃$
D) $0.00066\ per℃$
Explanation
(b) As we know $\gamma_{real} = \gamma_{app.} + \gamma_{vessel}$
$\Rightarrow \gamma_{app.} = \gamma_{glycerine} - \gamma_{glass}$
$= 0.000597 - 0.000027 = 0.00057/^{o}C$
