Anything that has mass and occupies space is called matter. A matter is made up of tiny particles. These particles are invisible to the naked eye.
Characteristics of the matter
The following are the characteristics of the matter:
- Particles have space between them
- Particles are continuously moving
- Particles attract each other
Classification of matter
Based on the intermolecular forces of attraction and spacings between the particles matter is broadly classified into three categories:
These are tightly packed because of strong intermolecular forces.
The molecules in a liquid are closely packed due to weak intermolecular forces.
The intermolecular forces Present between them are negligible.
