In reality, however, an ideal gas is subjected to intermolecular forces.

Large quantities of energy are required to overcome intermolecular forces.

In general one distinguishes short and long range intermolecular forces.

So this means that intermolecular attractive forces must come from some kind of electromagnetic force.

Rather the energy is used to break the intermolecular forces holding the water molecules in a liquid state.

The questions you should now ask are: What type of intermolecular attractive force exhibited by these molecules?

Real gases experience some of these collisions and intermolecular forces.

Other early work of London was in the area of intermolecular forces.

Ordinary matter takes its form as a result of intermolecular forces between individual molecules in matter.

Since its concepts still pervade the theory of intermolecular forces, it will be presented here.
