FAQs on Diffusion: Means of Transport Video Lecture - Biology for Grade 11
| 1. What is diffusion and how does it occur in living organisms? |  |
Ans. Diffusion is the process by which particles move from an area of higher concentration to an area of lower concentration. In living organisms, diffusion occurs across cell membranes, allowing for the movement of substances such as oxygen, carbon dioxide, and nutrients. This occurs due to the natural random motion of particles.
| 2. Can diffusion occur in both liquids and gases? | |
Ans. Yes, diffusion can occur in both liquids and gases. In liquids, particles move and mix with one another, resulting in diffusion. Similarly, in gases, particles move randomly and spread out, leading to diffusion. The rate of diffusion may vary depending on factors such as temperature, pressure, and concentration gradient.
| 3. How does temperature affect the rate of diffusion? | |
Ans. Temperature has a significant impact on the rate of diffusion. As temperature increases, particles gain more kinetic energy, leading to faster movement and collisions. This increased movement and collisions result in a higher rate of diffusion. Conversely, lower temperatures lead to slower diffusion rates due to reduced particle movement.
| 4. Can diffusion occur in solids? | |
Ans. Diffusion can occur in solids, although it is generally slower compared to liquids and gases. In solids, diffusion happens through the movement of atoms or molecules within the structure of the solid. This movement allows particles to spread out and mix, albeit at a slower pace than in liquids or gases.
| 5. How does the size of particles affect diffusion? | |
Ans. The size of particles has a direct influence on the rate of diffusion. Smaller particles diffuse more rapidly compared to larger ones. This is because smaller particles have a larger surface area-to-volume ratio, allowing for more efficient and quicker diffusion. Larger particles have a lower surface area-to-volume ratio, resulting in slower diffusion rates.
