A metallic bob weights `50 g` in air. If it is immersed in a liquid at a temperature of `25^@ C`, it weights `45 g` . When the temperature of the liquid is raised to `100^@ C`, it weights `45.1 g`. Calculate the coefficient of cubical expansion of the liquid. Given that coefficient of cubical expansion of the metal is `12 xx 10^(-6) .^@ C^-1`.
