1.	A platinum sphere floats in mercury. Find the percentage change in the fraction of volume of sphere immersed in mercury when the temperature is raised by 80∘C (Volume expansivity of mercury is 182×10−6/∘C and linear expansivity of platinum is 9×10−6/∘C)
Answer» A platinum sphere floats in mercury. Find the percentage change in the fraction of volume of sphere immersed in mercury when the temperature is raised by $80^{\circ} C$ (Volume expansivity of mercury is $182 \times 10^{- 6} /^{\circ} C$ and linear expansivity of platinum is $9 \times 10^{- 6} /^{\circ} C$ )
