WebThey are INTERmolecular forces, meaning you need to have at least two molecules for the force to be between them. For example, you have London Dispersion forces between two molecules of water in a setting but you … WebSep 17, 2024 · The molecular range is different for different substances. In solids and liquids, it is of the order of 10 -9 m. If the distance between the molecules is greater than 10 -9 m, the force of attraction between them is negligible. Surface tension has been well- explained by the molecular theory of matter. According to this theory, cohesive forces ...
