THE DEFINITION OF MATTER
Matter is defined as anything that has weight (mass) and occupies space. It could be rigid or non-rigid. e.g. paper, water, stone etc. The mass of an object is the quantity of matter an object contains and it is the same everywhere. The S.I unit of mass is kilograms (Kg).
Matter exists in three (3) physical states:
- Solid: it has a definite shape and volume.
- Liquid: it has a definite volume but no shape.
- Gas: it has no definite shape nor volume.
Movement of Particles
Matter is made up of tiny particles which are in constant motion, therefore possess kinetic energy.
