Diffusion

• Diffusion


  The net movement of gas particles, or particles in solution, from a region of high concentration to a region of low concentration
• The greater the concentration gradient between areas, the faster the rate of diffusion - more particles available to diffuse
• Greater surface area of the membrane increases the rate of diffusion - particles will have more surface area to access so more likely a particle will go through
• Shorter the distance for particles to travel increases the rate of diffusion - as particles will not have to travel far taking less time
• more movement will increase the rate of diffusion - increase kinetic energy lead to an increase in speed of particles
• higher temperatures increase the rate of diffusion - particles move faster at a higher temperature so have more kinetic energy
