What will be the difference in volume of water when it is heated from $0\,^oC$ to $10\,^oC$ ?
Initially (from $0^{\circ} \mathrm{C}$ to $4^{\circ} \mathrm{C}$ ) volume decreases and then (from $4^{\circ} \mathrm{C}$ to $10^{\circ} \mathrm{C}$ ) volume increase.

A sphere of diameter $7\,\, cm$ and mass $266.5 \,\,gm$ floats in a bath of a liquid. As the temperature is raised, the sphere just begins to sink at a temperature $35^o C$. If the density of a liquid at $0^o C$ is $1.527 \,\,gm/cc$, then neglecting the expansion of the sphere, the coefficient of cubical expansion of the liquid is$f$ :

A beaker of height $H$ is made up of a material whose coefficient of linear thermal expansion is $3\alpha $ . It is filled up to the brim by a liquid whose coefficient of thermal expansion is $\alpha $. If now the beaker along with its contents is uniformly heated through a small temperature $T$ the level of liquid will reduce by (given $\alpha << 1$)
