Matter can be classified on the basis of state into three categories :

Gas: It consists of molecules separated wide apart in empty spaces. These molecules are free to move in the container.

(ii) Liquid: The molecules in a liquid are comparatively closer to each other than gaseous molecules. They also have the freedom of movement within the system.

(iii) Solids: The molecules, atoms or ions are arranged in a certain order in fixed positions in the crystal lattice. They however do not have the freedom of movement.
