Two identical cylindrical vessel with their bases at the same level each contain a liquid of density rho . The height of the liquid in one vessel is h_(1) and in the other is h_(2) the area of either base is A. What is the work done by gravity is equalising the levels when the two vessels are connected?

Two identical cylindrical vessels with their bases at the same level each, contain a liquid of density rho . The area of either base is A but in one vessel the liquid heigth is h_(1) and in the other liquid height is h_(2)(h_(2)lth_(1)) . If the two vessel are connected, the work done by gravity in equalizing the level is

Two identical flasks - one filled with water to the "500 cm"^3 mark, and the other filled with kerosene to the same "500 cm"^3 mark are measured on an electronic balance. The flask filled with water is found to weigh 620 g, and that filled with kerosene weighs 520 g. The empty flask is measured and found to be 120 g. Find the densities of water and kerosene.

A beaker of height H is made up of a material whose coefficient of linear thermal expansion is 3alpha . It is filled up to the brim by a liquid whose coefficient of volume expansion is alpha . If now the beaker along with its contents is uniformly heated through a small temperature T, the level of liquid will reduced by ("Given, " alphaT ltlt 1)
