Solids are having particles closely packed.e.g. Chalk

Liquids are having loosly packed molecules.e.g.water

Gases having freely moving particles.e.g.ixygen gas in atmosphere.

Answer 2

I am telling with a example for better understanding

ex. water

when we heat it it becomes water that is liquid

when we heat water it becomes vapour that is gas

when we freeze vapour it is water that is again liquid
