Surface tension of a liquid is numerically equal to

A liquid drop of density rho is floating half immersed in a liquid of surface tension S and density rho/2 . If the surface tension S of the liquid is numerically equal to 10 times of acceleration due to gravity, then the diameter of the drop is :

Surface tension in a liquid is due to :

explain what is meant by surface energy of a liquid. Show that surface energy per unit area is numerically equal to the surface tension.

Surface tension of a liquid is a molecular phenomenon of liquids involving the force of cohesion along the liquid molecules. It is scalar quantity and is numerically equal to the surface energy. Numerically, it is proved that the potential soluble salts and surface active substance. Sparingly soluble salts and surface active substances decrease the surface tension of the liquid. However, the fairly soluble solutes increase the surface tension of the liquid. Surface tension of a liquid is independent of surface area but it depends on the intermolecular forces and the temperature. Surface tension of a liquid does not depend on :
