Which of the following curves represent the variation of coefficient of volume expansion of an ideal gas at constant pressure?

The coefficient of volumetric expansion of mercury is $18 \times 10^{-5} \, ^\circ C^{-1}$. $A$ thermometer bulb has a volume $10^{-6} \, m^3$ and the cross-section of the stem is $0.004 \, cm^2$. Assuming that the bulb is filled with mercury at $0 \, ^\circ C$,find the length of the mercury column at $100 \, ^\circ C$.

With a rise in temperature,the density of a given body changes according to which of the following relations?

"Anomalous expansion of water is a blessing for living organisms in water." Explain this statement. Explain the anomalous expansion of water.

In an experiment to find the liquid expansion coefficient $(\gamma)$,a column of experimental liquid at $T\,^oC$ is balanced against another column of experimental liquid at $0\,^oC$ by taking them in a $U$-tube. The expansion coefficient $(\gamma)$ is?

The densities of a liquid at $0^{\circ} C$ and $100^{\circ} C$ are respectively $1.0127 \ g/cm^3$ and $1 \ g/cm^3$. $A$ specific gravity bottle is filled with $300 \ g$ of the liquid at $0^{\circ} C$ up to the brim and it is heated to $100^{\circ} C$. Then,the mass of the liquid expelled in grams is: (Coefficient of linear expansion of glass $= 9 \times 10^{-6} /^{\circ} C$)
