- In liquid the particles are a little far away from each other but they have a powerful attractive force in between them by which we can separate them into layers of density
 - On the other hand in gas the particles are too far apart from each other so we can't separate them into layers of density.
 
There are 5states of matter
- Solid
 - Liquid
 - Gas
 - Bose-Einstein Condensation
