DILUTION
1. Place a crystal of potassium manganate(VII) in a beaker of water.
2. The color spreads through the water.
3. Over time you can see the color levels out but it is weaker than the original colour.
This is because particles leave the crystal, it dissolves. Then they mix among the water particles.

DIFFUSION
1. Place an open gas jar of air upside down on an open gas jar containing a few drops of red-brown bromine.
2. The color spreads upwards
This is because the particles of bromine vapour mix among the particles of air.
