Question

The absolute coefficient of expansion of a liquid is 7 times that the volume coefficient of expansion of the vessel. Then the ratio of absolute and apparent expansion of the liquid is

• A. (a) $\frac{1}{7}$
• A. (b) $\frac{7}{6}$
• A. (c) $\frac{6}{7}$
• A. (d) None of these

Answer 1

(b)

Apparent coefficient of Volume expansion γ_app. = γ_L – γ_s = 7 γ_s – γ_s = 6γ_s (given γ_L = 7 γ_s )

Ratio of absolute and apparent expansion of liquid $\frac{\gamma_{L}}{\gamma_{app.}} = \frac{7\gamma_{s}}{6\gamma_{s}} = \frac{7}{6}$.
