1.	A metallic bob of weight 100 gm is suspended in air. If it is immersed in a liquid at temperature of 30∘C, it weighs 90 gm. When the temperature of the liquid is raised to 100∘C, it weighs 90.2 gm. Calculate the coefficient of cubical expansion of the liquid. Given that coefficient of cubical expansion of the metal is 15×10−6/∘C
Answer» A metallic bob of weight $100 gm$ is suspended in air. If it is immersed in a liquid at temperature of $30^{\circ} C$ , it weighs $90 gm$ . When the temperature of the liquid is raised to $100^{\circ} C$ , it weighs $90.2 gm$ . Calculate the coefficient of cubical expansion of the liquid. Given that coefficient of cubical expansion of the metal is $15 \times 10^{- 6} /^{\circ} C$
