diffusion

• Diffusion occurs in one direction while equal diffusion occurs in the other direction which causes particle movement however no overall diffusion
• The speed of diffusion is affected by the concentration gradient, temperature, and size of particles
• increased temperatures causes faster particle movement
• smaller particles move quicker
• high concentration: more particles
• low concentration: less particles
• the result of diffusion is equal concentration in both sides

  
• another word for equal concentration is equilibrium
• diffusion is the movement of particles from an area of high concentration to an area of low concentration
