Chemistry

The Classification of Matter


Some definitions

Some Definitions

  • Pure Substance: A substance that is made up of only one type of particle. i.e Distilled water

    • Tap water has dissolved gases in it.

  • Mixture: Contains more than one type of particle

    • Solid mixture -> cell phone, cereal

    • Liquid mixture -> tea, juice

    • Gas mixture -> air


Types of mixtures

Types of Mixtures

  • Mechanical Mixture: You can distinguish between different types of matter. i.e. granola bar & pizza.

  • Solutions: A uniform mixture of two or more substances. i.e. clear apple juice.

    • Note: All liquid and gas solutions are clear! If a liquid or gas mixture appears murky or opaque, it is a mechanical mixture.

  • Alloy: A solid solution of two or more metals.

    • i.e. Bronze -> Copper + Tin
