To understand consider a soap solution film. Suppose it's thickness is 1 micron. Now, size of molecule as building blocks of the film is of the order of 10^(-10) m. This means that when we go from one side of the surface to the other side and count the number of molecules, it comes out to be roughly10,000. read more

Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties. read more
