  1. The forces that hold condensed states together Structure of the particles determine the strength of the intermolecular forces Intermolecular Forces Oringinate from the interactions between charges partial charges temporary charges Liquid, Solids2 protons and electrons are attracted to each other because their potential energy decreases as they get closer together Similarly, molecules with partial or temporary charges are attracted to each other because their potential energy decreases as they get closer together. Intermolecular forces, even the strongest ones, are generally much weaker than bonding Coulomb's law forces. Reason for the relative weakness of intermolecular forces compared to bonding forces Bonding forces are the result of large charges (the charges on protons and electrons) interacting at very close distances Intermolecular forces are the result of smaller charges interacting at greater distances Consider interaction between two water molecules in liquid water: The length of an O-H bond in liquid water is 96 pm The average distance between water molecules in liquid water is about 300 pm The larger distances between molecules, as well as the smaller charges involved (the partial charges on the hydrogen and oxygen atoms), result in weaker forces. To break the O-H bonds in water, we have to heat the water to thousands of degrees Celsius To completely overcome the intermolecular forces between water molecules, we have to heat water only to its boiling point, 1000C (at sea level).
