Study Notes
- Today's lesson on Grade 8 science is about the properties of matter.
- Matter is anything that has mass and volume, occupies space.
- Matter can be classified as solid, liquid, and gas based on the nature of particles.
- Solid matter has a definite shape and volume, particles are close together, and forces between them are strong.
- Liquid matter takes the shape of its container, particles move freely, and it has a definite volume but not a definite shape.
- Gas matter has no definite shape or volume, particles move quickly and can break away completely from one another.
- Matter is made up of tiny particles called atoms or molecules, which are in constant random motion and held together by attractive forces.
- Solid particles have fixed positions, while liquid and gas particles have empty spaces between them.
- Atoms and particles of matter are almost everywhere and can be identified as solid, liquid, or gas.
