Factors Affecting Diffusion
Diffusion is a vital process for life, but its speed depends on several environmental and structural factors.
What happens to diffusion if the temperature rises?
What is Factors Affecting Diffusion?
"Factors affecting diffusion are variables such as temperature and gradient that determine the speed at which particles move."
Diffusion is the net movement of particles:
Which change would increase the rate of diffusion?
In the lungs, oxygen moves from the alveoli into the blood by:
The Three Factors
Concentration gradient: The bigger the difference, the faster the diffusion.
Temperature: Higher temperature means particles have more kinetic energy.
Surface Area: More space for particles to pass through increases the rate.
Short diffusion paths (thin membranes) also significantly increase the exchange rate.
