Diffusion

• Diffusion


  Movement of particles from high concentrantion to low concentration down a concentration gradient
• Why is diffusion passive?


  It requires no energy
• Solid's version of diffusion (kinda)

  • Dissolving
  • Dissolve particles spread around
• Factors Affecting DIffusion:


  • State of matter
  • Temp - higher = faster
  • Particle size - smaller = faster
  • Concentration gradient - bigger faster
