Factors that Affect Diffusion Rate

The video tutorial explains the factors affecting diffusion rate, including molecular weight, concentration gradient, surface area to volume ratio, and heat. Molecular weight has an inverse relationship with diffusion rate, while the other factors have direct relationships. The tutorial uses analogies and examples to illustrate these concepts, emphasizing the importance of understanding these factors for biological processes.

What happens to the diffusion rate when the concentration gradient is increased?

In what way does the structure of the small intestine facilitate diffusion?

Why is it important for organisms to have a high rate of diffusion?

Summarize the four factors that affect diffusion rate.
