Bongani says that helium (( ext{He})) is an ion and so . Dispersion acts on any two liquid molecules that are close together. Viscosity decreases rapidly with increasing temperatures because the kinetic energy of the molecules increases, and higher kinetic energy enables the molecules to overcome the attractive forces that prevent the liquid from flowing. There are 3 types, dispersion forces, dipole-dipole and hydrogen bonding. fatsia japonica leaf problems; godzilla diorama buildings; lidl fish fingers calories Of these, the hydrogen bonds are known to be the strongest. In a solution of water and ethanol, hydrogen bonding is the strongest intermolecular force between molecules. However because a hydrogen atom is covalently bonded to a fluorine atom, and the same hydrogen atom interacts with a fluorine atom on another HF molecule, hydrogen bonding is possible. chem. Hydrogen bonding is a special type of intermolecular attraction between the hydrogen atom in a polar bond (particularly H-F, H-O, and H-N) and nonbonding electron pair on a nearby small electronegative ion or atom (usually F, O, or N in another molecule).
