Document Summary

Intramolecular forces: forces within a molecule, hold the atoms making up molecule. Intermolecular forces: forces between molecules, not as strong as intramolecular attractions that hold components together, Lo many physical properties are in uenced by them, like boiling points melting points viscosity (htce) hace strong intermolecular surface tension tweak - attraction (covalent) capillary action intermolecular attraction. Difference is the strength of the intermolecular forces of attraction: solids and liquids = condensed phases. ~ which state of matters depends on: w kinetic energies of particles. Linter particle energies of attraction intermolecular forces a cohesive forces vas - kinetic energies > energies of attraction.
