Problem

A metallic bob weighs 50 g in air. If it is immersed in a liquid at a temperature of

25^\circ \text{C}

, it weighs 45 g. When the temperature of the liquid is raised to

100^\circ \text{C}

, it weighs 45.1 g. Calculate the coefficient of cubical expansion of the liquid. Given that coefficient of cubical expansion of the metal is

12 \times 10^{-6} \text{ } ^\circ\text{C}^{-1}
