NEET Physics Thermal Properties Of Matter Thermal Expansion Of Liquids MCQs

A glass flask is completely filled with mercury at $20^\circ C$. If the flask and mercury are heated to $40^\circ C$, what fraction of the mercury will overflow? (Given: Coefficient of volume expansion of mercury, $\gamma_{Hg} = 1.82 imes 10^{-4} \, K^{-1}$; Coefficient of linear expansion of glass, $\alpha_{glass} = 9 imes 10^{-6} \, K^{-1}$)

Which of the following liquids has the highest anomalous expansion?

Two identical thermometers, one filled with mercury and the other with alcohol, are placed in a hot water bath. Which thermometer will show a quicker rise in temperature?

A steel container is filled to the brim with kerosene at $10^\circ C$. If the temperature is increased to $30^\circ C$, what will happen?

The coefficient of real expansion of a liquid is $\gamma_r$ and the coefficient of apparent expansion of the liquid in a vessel is $\gamma_a$. The coefficient of volume expansion of the vessel is:

Why does the level of mercury in a thermometer first fall slightly before rising when placed in hot water?

A glass flask is completely filled with mercury at $20^\circ C$. When the temperature is raised to $80^\circ C$, some mercury overflows. If the coefficient of volume expansion of glass is $27 imes 10^{-6} \, K^{-1}$ and that of mercury is $180 imes 10^{-6} \, K^{-1}$, the ratio of the mass of mercury overflowing to the mass initially in the flask is:

Which of the following has the highest coefficient of volume expansion?

The anomalous expansion of water occurs between:

Two liquids A and B have coefficients of volume expansion $\gamma_A$ and $\gamma_B$ respectively, where $\gamma_A > \gamma_B$. If equal volumes of A and B are heated through the same temperature range, which liquid will expand more?
