Going from gas to liquid to solid, molecular velocities and particle separations diminish progressively as structural order increases. The universal repulsive force arises directly from two main aspects of quantum theory: the Heisenberg uncertainty principle and the Pauli exclusion principle. INTRAmolecular force: holds atoms together in an ionic, covalent or metallic bond. Therefore according to this statement gases will have the higher kinetic energy in comparison to intermolecular forces, solids will gave greater intermolecular forces in comparison to kinetic energy, and liquids are in the middle with kinetic energy less than intermolecular forces but not as significant of a difference in comparison to solids.

This is the average distance that will be maintained by the two particles if there are no other forces acting on them, such as might arise from the presence of other particles nearby. For example, an uncharged molecule will not have a monopole moment and hence will not have monopole-monopole IMF, nor monopole-dipole or monopole-quadrupole IMFs. Intermolecular Forces Worksheets Key. Often, but not always, these interactions can be ranked in terms of strengths with of interactions involving lower number of moments dominating those with higher moments. The forces that hold molecules together in the liquid and solid states are called intermolecular forces and are appreciably weaker. Correspondingly, if \(q_1\) and \(q_2\) have the same sign, then the force is negative (i.e., a repulsive interaction).
