Matter exists in three states, solid, liquid, and gas. There are many properties associated with matter. For example, the matter has weight and occupies space.

There are some other propertiesthath are associated with one state of matter but not with others. For example, solids have tashape of their own while liquids and gases do not. Liquids on the other hand have definite volume while gases do not. Various materials differ in their hardness, density, solubility, flow, elasticity, conductivity, and many other qualities. The kinetic molecular model helps in understanding the properties of matter in a simplified way.
