When the surface of the liquid is strong enough, then surface tension is applicable. For example, the attractive force between molecules of iron is the Cohesive force. In Physics, the tension of the surface film of a liquid because of the attraction of the surface particles by the bulk of the liquid, which tries to minimize surface area is called surface tension. Studies on random packing of bidispersive particles have shown that such systems can capture the underlying behavior of more complex phenomena found in physics and materials engineering. from the electro-static interaction of the electron density with the ions and the ion-ion interaction. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of surrounding electrons irregular when molecules get close to one another, creating electrical attraction that can maintain a microscopic structure such as a water drop. Cohesion is an intrinsic property of a molecule, determined by its shape, structure, and electric charge distribution.
