Factors That Affect Diffusion

Question 1

1. Particle size

Answer 1

The smaller particles will diffuse more quickly and depending on the size large molecules may not diffuse at all

Question 2

2. Temperature

Answer 2

Increased temperature increases particle movement

Question 3

3. Concentration

Answer 3

When a substance is diffusing between two compartments, the greater the concentration difference between the two compartments, the faster the substance Will diffuse

The higher the difference, the faster the movement.

Question 4

4. Surface area

Answer 4

The larger the surface area the greater the rate of diffusion

Question 5

5. Permeability

Answer 5

The more porous the substance is, the faster it can diffuse through it

-The size of the particle does not matter if there are no pores
