Key Topics to Revise
1
States of Matter
- Matter is anything that has mass and occupies space.
- There are three states of matter: solids, liquids, and gases.
- Solids have fixed shape and volume. Example: book, chair.
2
Molecular Arrangement in States
- Solids: Molecules are tightly packed and arranged in order. They cannot move freely.
- Liquores: Molecules are loosely packed and can move around each other.
- Gases: Molecules are far apart and move quickly in all directions.
3
Changes in States of Matter
- Melting: Solid changes to liquid on heating. Example: Ice → Water.
- Freezing: Liquid changes to solid on cooling. Example: Water → Ice.
- Evaporation: Liquid changes to gas on heating. Example: Water → Steam.
4
Solutions and Separation Methods
- A solution is formed when a solute dissolves in a solvent. Example: Salt (solute) in Water (solvent).
- Types of solutions: Solid in liquid (sugar-water), Liquid in liquid (lemon-water), Gas in liquid (soda).
- Insoluble solids (like sand) can be separated by sedimentation, decantation, or filtration.
