What is diffusion?

• The random movement of particles due to collisions.
• The change in concentration from a high concentration area to a low concentration area.
• The movement of particles from a region of lower concentration to a region of higher concentration.
• The process of how particles spread out from an area of high concentration to an area of low concentration.

What is the relationship between Brownian motion and diffusion?

• Brownian motion is the movement of particles from a region of lower concentration to a region of higher concentration.
• Brownian motion is the random movement of particles due to collisions.
• Brownian motion is the process of how particles spread out from a high concentration area to a low concentration area.
• Brownian motion is the change in concentration from a high concentration area to a low concentration area.
