Diffusion

• What type of process is diffusion?

  Passive process
• What is diffusion?

  Diffusion is the spreading out of particles resulting in net movement from higher to lower concentration.
• What causes diffusion to occur?

  It results in a net movement from an area of higher concentration to an area of lower concentration.
• How does temperature affect diffusion?

  Higher temperature causes particles to move more quickly, resulting in faster diffusion.
• What happens to the rate of diffusion at cold temperatures?

  Cold temperatures slow down the rate of diffusion.
• How does the concentration gradient affect diffusion?

  The greater the difference in concentration, the faster diffusion will occur.
• What is the effect of surface area on diffusion?

  A larger surface area speeds up the rate of diffusion.
• What are the factors affecting diffusion?

  • Temperature
  • Concentration gradient
  • Surface area
