Kinetic theory of matter tries to explain all molecules in terms of motion. The theory posits that every substance consists of many small particles referred to as molecules. Substances in this case are called matter and are in three forms; solids, liquids, and gases. Solids have molecules that are closer to each other by intermolecular forces. Liquids on the other hand have molecules slightly far apart with gases the furthest apart. Furthermore, according to this theory all the molecules are in constant random motion referred to as Brownian motion (Chang, 2004).
