A vessel contains oil (density 0.8gm/c.c) over mercury (density 13.6 gm/c.c). A homogeneous sphere floats with half its volume immersed in mercury and the other half in oil.What is the density of the material of the sphere in gm/c.c?

There is a layer of oil over mercury in a container. The density of mercury is 13.6g*cm^(-3) and that of the oil is 0.8g*cm^(-3) . A homogeneous sphere remains immersed with half of its volume in mercury and the other half in oil. The density of the material of the sphere in g*cm^(-3) is

What is the density of pure water at 4^(@)C in SI?

The external and internal diameters of a hollow sphere are 6 cm and 8 cm respectively. The sphere floats completely immersed in a liquid of density 1.2g*cm^(-3) . What is the density of the material of the sphere?

What change will be observed if both mercury and water are heated from 0^(@)C ?

A 1 L flask contains some mercury. It is observed that the volume of air in the flask remains unchanged at all temperatures. What is the volume of mercury in the flask? Coefficient of linear expansion of the material of the flask =9 times 10^(-6@)C^(-1) and coefficient of real expansion of mercury =1.8 times 10^(-4@)C^(-1)
