On what basis are three states of matter?

On the basis of Physical State, the three states of matter are classified. This depends upon the arrangement of atoms in the matter.

Three states of matter exist in solid, liquid, and gas.

Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviours of these particles differ in the three phases.

• Solids have a definite shape and volume as the atoms in solid are tightly packed, usually in a regular pattern.

• Liquids have a definite volume, but take the shape of the container, as the atoms in liquid are close together with no regular arrangement.

• Gases have no definite shape or volume. The atoms in the gas are well separated with no regular arrangement.
