– are forces that exist between molecules.
– this force holds the molecules together which can be attractive or repulsive. – – these attractive forces are much weaker than bonding forces.
– determines the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.
– are accountable for the properties of substances.
– explain why substances exist as solids, liquids, or gases at room temperature.
