Diffusion

• Osmosis a specific type of diffusion
• the diffusion of water molecules through a selective permeable membrane (osmosis)
• The water moves from a solution of low solute concentration to a higher solute concentration (osmosis)
• Diffusion makes the particles move in all directions
• Diffusion is a passive process
• the speed of diffusion is affected by two things temperature and size of the concentration gradient
• Temperature 


  increasing the temperature will speed up diffusion as is makes the particles move faster
• The size of concentration gradient

  the bigger the concentration gradient, the faster diffusion will be
