Key Topics to Revise
1
What is Matter?
- Matter is anything that has mass and occupies space.
- Examples: book, water, air, chair, plants, animals.
- Even air is matter, though we cannot see it. We can feel it when the wind blows.
2
Composition of Matter: Atoms and Molecules
- Matter is made up of very tiny particles called atoms.
- Atoms combine to form molecules. A molecule is the smallest unit of matter that can exist independently.
- Example: A water molecule (H₂O) has 2 hydrogen atoms and 1 oxygen atom.
3
States of Matter
- Matter exists in three states: solid, liquid, and gas.
- Solids have fixed shape and volume. Example: ice, wood.
- Liquids have fixed volume but no fixed shape. They take the shape of the container. Example: water, milk.
4
Interconversion of States of Matter
- Matter can change from one state to another by changing temperature or pressure.
- Melting: Solid → Liquid (e.g., ice to water).
- Freezing: Liquid → Solid (e.g., water to ice).
