Iron floats over mercury because density of mercury is more than the density of iron. Coefficient of volumetric expansion of iron and mercury are35 xx 10^(-6)""^(@) C^(-1).and 180 xx 10^(-6)""^(@) C^(-1). Now consider an iron cube floating in a bowl of mercury at 0^(@) C. When temperature is increased upt0 25^(@)C. then choose the correct options.

1.	Iron floats over mercury because density of mercury is more than the density of iron. Coefficient of volumetric expansion of iron and mercury are35 xx 10^(-6)""^(@) C^(-1).and 180 xx 10^(-6)""^(@) C^(-1). Now consider an iron cube floating in a bowl of mercury at 0^(@) C. When temperature is increased upt0 25^(@)C. then choose the correct options.
Answer» Cube submerges more at 25°C Cube DISPLACED more at 25°C Percentage CHANGE in the FRACTION of volume submerged is about 1 % Percentage change in the fraction of volume submerged is about 0.4% ANSWER :A::D
