### Theory:

Everything in this universe is made up of material which scientists have named matter.

Take a moment to look at our surroundings, we see a variety of things with different shapes, sizes and textures. The water we drink, the food we eat, the cloths we wear, and the air we breath everyday. Each of these things have their own mass and volume.

According to our ancient  Indian philosophers every living or non-living, thing was made up of these five basic elements named the Panch Tatva. The five basic elements are air, earth, fire, sky and water.

But our modern day scientists have proposed two types of classification of matter based on their physical properties and chemical nature.

And we shall learn about matter based on its physical properties and chemical aspects of matter.

Physical properties:
Matter contains $$n$$ number of  particles. The particles of matter are very small which is beyond our imagination!
Let see an example to understand this clearly.
Example:

Take a beaker or a medium size bowl with water and dissolve some sugar with the help of a glass rod. Wait for few seconds. and can you observe any changes on the water level?

What happed to those sugar particles?

We already know that the particles are very tiny in nature. When we dissolve sugar in water, the particles of sugar get into the spaces between particles of water. So that why the water level is not raised.
And think about what will happen if you add the medium size stones instead of sugar particles.

If you're thinking that the water level will definitely raise, yes you're right.

Conclusion:
• Everything in this universe is made up of matter.
• Generally matters occurs in solid, liquid and gas.
• Matter consist of tiny particles.
