Q. If on heating liquid through $80℃$, the mass expelled is $(1/100)^{th}$ of mass still remaining, the coefficient of apparent expansion of liquid is
A) $1.25 \times 10^{- 4}/℃$
B) $12.5 \times 10^{- 4}/℃$
C) $1.25 \times 10^{- 5}/℃$
D) None of these
Explanation
(a) $\gamma_{app.} = \frac{Mass\ expelled}{Mass\ remained\ \times \mathrm{\Delta}T}$
$= \frac{x/100}{x \times 80} = \frac{1}{8000} = 1.25 \times 10^{- 4}/℃$
