What process is shown here?

What is diffusion?

Main ideas involved in diffusion

• particles move from a region of HIGH to LOW concentration until equilibrium
• the rate of diffusion in liquids is much SLOWER than in gases
• diffusion does NOT take place in solids as the particles cannot move from place to place

DIFFUSION

• a process by which different fluids mix as a result of the random motions of their particles
