what is diffusion ks3
Diffusion in liquids. Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed. For example if you drop a little bit of paint into a jar of water the colour will spread slowly through the water.This is by diffusion.Diffusion in liquids is slower than diffusion in gases because the particles in a liquid move more slowly.ou don't have to mix the gases by waving your arms around-it mixes on its own. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases. Diffusion happens quickly in gases.
