Like dissolves like - Species of similar polarity attract each other as much as their own kind. Disruptive force described by kinetic theory. Atoms, molecules, ions of substance are in continuous, rapid, random motion. Gas - Disruptive forces dominate. Little attraction between atoms or molecules.
Particles act independently but can exchange energy in collisions.
Solid - Attractive forces predominate. Strong attractive forces lead to high melting and boiling points. For a given substance, phase is determined by temperature. Vapor pressure and boiling.
