Three states of matter

What you need to learn in this topic

1. Generalise that matter consists of particles
2. Compare and contrast three states of matter based on the kinetic theory in terms of the arrangement and movement of particles
3. Use space-time relationships to compare rate of diffusion in three states of matter
4. Describe the change in state of matter, in terms of movement of particles caused by the absorption and the release of heat, based on kinetic theory
5. Conclude that temperature remains constant during freezing, melting and boiling
6. Conclude that the mass remains constant during physical changes
7. Explain with examples the changes of the state of matter in daily life
