Surface Tension of Water Explained

Surface tension in liquid water resists an external force because of cohesive nature (due to hydrogen bonding) of its molecules. Water molecules on the surface of water differ in that they can make fewer hydrogen bonds than water molecules at the center of the liquid. As a result the water molecules are more strongly attracted, and surface tension is present.
