Content

Activity: to explain the three basic forms of matter in terms of particle theory [lo 2.2]

  • SOLID SUBSTANCES
  • LIQUIDS
  • GASES

The particles in a solid substance remain in place and move very little. They vibrate in a fixed position. This is why solids have a fixed shape and volume. The particles form a regular pattern.

In liquids, the particles are able to move freely, but they cannot go far from one another. They do not have a fixed pattern and can therefore take the form of the container in which they are. As the particles are unable to move far from one another, the volume cannot really change.

The particles of a gas can more or less move to any place. These particles are also much further apart than the particles in a liquid or a solid substance.

Assignment 3

See whether you are able to complete the following columns by listing examples of substances that represent the three forms of matter.

Solid substances Liquid substances Gases
  • Iron
  • Water
  • Carbon dioxide

Assessment

Learning Outcome 2: The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.
