*Anything that occupies space and has mass and is felt by senses is called matter.

Matter is the form of five basic elements that is called punch tantra -Air,Earth,Fire,Sky and Water.

*Characterstics of particles of matter

1.Made of tiny particles.

2.Vacant spaces exist in particles.

3.Particles are in continuous motion.

4. Particles are held together by forces of attraction.

5.Particles of matter have space between them.

6.As the temperature rises , particles move faster. So, we can say that with increase in temperature the kinetic energy of the particles also increase.

7.particles of matter attract each other. The strength of this force of attraction varies from one matter to another

Diffusion: The intermixing of particles of two different types of matter on their own is called diffusion.
