Diffusion gives you four interactive animations to simulate the common classroom experiments.

You’ll use it to:

• Show how common observations of diffusion relate to the particle model.
• Show how diffusion occurs in liquids and gases.
• Show how diffusion explains what happens when coloured crystals dissolve.
• Explain why a liquid evaporates more quickly into vacuum than into another gas.
• Explain how and why temperature affects the rate at which diffusion occurs.
