Abstract

Surface tension is the physical property of the surface of a liquid to resist an external force. The intermolecular bonds or cohesive forces between the molecules of a liquid cause surface tension; this tension is due to intermolecular forces, which are the same forces that cause molecules to compress into a liquid.  Factors having influence on surface tension includes chemical nature, temperature and presence of solute. Chemical nature like polar solvents tends to increase surface tension in other hand an increase in temperature tends to cause surface tension to fall.
