Understand the concept of diffusion: Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. It is a passive process driven by the kinetic energy of particles.
Identify the main factors affecting the rate of diffusion: These include surface area, temperature, and concentration gradient. Each of these factors influences how quickly particles can move and spread out.
Explain how surface area affects diffusion: A larger surface area allows more particles to pass through at once, increasing the rate of diffusion.
Discuss the role of temperature in diffusion: Higher temperatures increase the kinetic energy of particles, causing them to move faster and thus increasing the rate of diffusion.
Clarify the impact of concentration gradient on diffusion: A steeper concentration gradient (a larger difference in concentration between two areas) results in a faster rate of diffusion as particles move to equalize concentrations.
