Matter is anything that occupies space and has mass, and is made up of particles. It exists in three states: solid, liquid, and gas. Solids have a fixed shape and volume, with little space between particles, making them incompressible. Liquids and gases have more space between particles and can flow or be compressed. Particles of matter are small, continuously moving, and attract one another but with space between them.

3. Characteristics of particles of matter

• Particles of matter are continuous in motion.
• Particles of matter are small in size.

4. States Of Matter
• There are three states of matter:-
• Solid
• Liquid
• Gases

5. SOLIDS
• Solids have fixed shape and volume.
• There intermecular space is less.
• They are incompressible.
