A metal ball immersed in Alcohol weights ${\mathrm{W}}_1$ at $0^{\circ }\mathrm{C}$ and ${\mathrm{W}}_2$ at $50^{\circ }\mathrm{C}$. The coefficient of cubical expansion of the metal $(\gamma {)}_{\mathrm{m}}$ is less than that of alcohol $(\gamma {)}_{\mathrm{Al}}$. Assuming that density of metal is large compared to that of alcohol, it can be shown that
