7.4. Classifying matter
Matter is all around us. As you have learned, depending on its state, we classify it into solids, liquids and gases.
We can classify it further depending on wether it is one type of matter or a combination of different kinds of matter.
Matter can be either a pure substance or a mixture.
- Pure substances are made up of only one type of matter.
- Mixtures are made up of two or more pure substances (two or more types of matter).
