Vedclass · Answer

(B) The coefficient of apparent expansion $\gamma_{app}$ is related to the coefficient of real expansion of liquid $\gamma_r$ and the coefficient of volume expansion of the vessel $\gamma_v$ by the formula: $\gamma_{app} = \gamma_r - \gamma_v$.For a vessel,the coefficient of volume expansion $\gamma_v = 3\alpha$,where $\alpha$ is the coefficient of linear expansion.Thus,$\gamma_{app} = \gamma_r - 3\alpha$.For steel: $\gamma_{app, steel} = 114 	imes 10^{-6} /^{\circ}C$ and $\alpha_{steel} = 12 	imes 10^{-6} /^{\circ}C$.$\gamma_r = \gamma_{app, steel} + 3\alpha_{steel} = 114 	imes 10^{-6} + 3(12 	imes 10^{-6}) = 114 	imes 10^{-6} + 36 	imes 10^{-6} = 150 	imes 10^{-6} /^{\circ}C$.For glass: $\gamma_{app, glass} = 132 	imes 10^{-6} /^{\circ}C$.Using $\gamma_{app, glass} = \gamma_r - 3\alpha_{glass}$:$132 	imes 10^{-6} = 150 	imes 10^{-6} - 3\alpha_{glass}$.$3\alpha_{glass} = 150 	imes 10^{-6} - 132 	imes 10^{-6} = 18 	imes 10^{-6} /^{\circ}C$.$\alpha_{glass} = 6 	imes 10^{-6} /^{\circ}C$.

The coefficient of apparent expansion of mercury in a glass vessel is $132 \times 10^{-6} /^{\circ}C$ and in a steel vessel is $114 \times 10^{-6} /^{\circ}C$. If $\alpha$ for steel is $12 \times 10^{-6} /^{\circ}C$,then that of glass is:
