Detailed Solution

The three general kinds of matter are determined by the intermolecular forces of attraction and the distances between the particles:
●        Solids: Strong intermolecular pressures cause these to be closely packed. Example: Sofa.
●        Liquids: Weak intermolecular forces cause the molecules of a liquid to be tightly packed. Example: Water
●        Gases: There are very few intermolecular forces between them. Consider air.
Anything that has volume and occupies space is considered matter. Electromagnetic radiation is the source of light. It has neither mass nor volume. It is not a liquid, a gas, or a solid.
Light cannot be categorised as matter as a result.
