Solids, Liquids and Gases

Solids, Liquids and Gases is an interactive simulation of the particle model.

YouÂ’ll use it to:

  • Explain how particles behave.
  • Show how the particlesÂ’ behaviour explains the properties of solids, liquids and gases.
  • Show why and how substances change state.
  • Compare particles in different substances.
  • Investigate how changing the attraction between particles affects melting and boiling points.
  • Run virtual cooling/heating curve experiments.
