Matter in Our Surroundings

What is matter made up of?

According to early Indian philosophers, which of these is NOT one of the five basic elements?

Matter is classified based on its physical properties and chemical nature.

What happens to salt when it is dissolved in water?

The SI unit of _______ is kilogram (kg).

The common unit of measuring volume is _______ (L).

How can we observe the movement of particles in matter?

What was the belief of one school regarding the nature of matter?

What happens when you light an incense stick?

Matter in Our Surroundings

Everything in the universe is made of matter.
Matter occupies space and has mass.
Early Indian philosophers classified matter into five basic elements: air, earth, fire, sky, and water.
Modern scientists classify matter based on physical properties and chemical nature.

Physical Nature of Matter

Matter is made up of particles.
Particles of matter are very small.

Matter is Made Up of Particles

The particle nature of matter can be demonstrated by dissolving salt or sugar in water.
The salt or sugar disappears, but it has spread throughout the water.
This suggests that the particles of salt or sugar are small enough to fit between the spaces in the water particles.

How Small are These Particles of Matter?

A small amount of potassium permanganate can color a large volume of water.
This demonstrates how small the particles of potassium permanganate must be.

Particles of Matter are Continuously Moving

You can smell incense from a distance, even if the stick is not lit.
When the stick is lit, the smell spreads more quickly.
This suggests that particles of matter are always moving, and they move faster when heated.
This can be demonstrated by placing two beakers filled with water next to each other.
The water in the beaker with the heated incense stick will warm up faster, as the heat from the incense stick causes the water particles to move more quickly.

Explore the fascinating world of matter, from its basic definitions to its classification and particle nature. This quiz covers the early philosophical views and modern scientific principles that outline how matter interacts with the universe around us. Get ready to test your understanding of how matter occupies space and the movement of its particles.
