It is the maximum distance upto which a molecule can exert some appreciable force of attraction on other molecules. It is of the order of 10″ 9<\/sup> m in solids and liquids.<\/p>\n\n\n\n Sphere of influence. A sphere drawn around a molecule as centre and with a radius equal to the molecular range is called the sphere of influence of the molecule. The molecule at the centre attracts all the molecules lying in its sphere of influence.<\/p>\n\n\n\n While studying the behaviour of a molecule under the influence of cohesive forces, we need to consider only the molecules lying in its sphere of influence.<\/p>\n\n\n\n Surface film:<\/p>\n\n\n\n A thin film of liquid near its surface having thickness equal to the molecular range for that liquid is called surface film.<\/p>\n","protected":false},"excerpt":{"rendered":" It is the maximum distance upto which a molecule can exert some appreciable force of attraction on other molecules.
