What is the reason for the existence of three states of matter

The reason why matter exists in three different states is due to inter-molecular forces between the molecules that make an element or a compound.
Matter picks up any of this three states as a result of the energy level possessed in it that determines the level of intermolecular forces.
When matter has very strong intermolecular forces and its molecules are packed together, it exits as a solid.
When the intermolecular forces are weaker and the molecules are not strongly attracted to each other, it exists as a liquid.
When these forces are very weak and almost negligible, the molecules of matter are free to roam around and it exists as gas.

Explanation:
The three states of matter exist due to the difference in the inter moleculer force of attraction between the molecules of the substance.
When the intermolecular force of attraction is strong and molecules are closely bound,then the matter exists as solid.When the intermolecular forces of attraction is weak and molecules are less closely packed,then the matter exists as liquids and when the intermolecular force of attraction are very weak and molecules are free to roam,then the matter exists as gas
