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.
