Question 1.
What is flux according to Fick's law?
Show hintHide hint
Think about the direction substances move in relation to concentration.
Question 2.
Name one factor that influences diffusion.
Show hintHide hint
Consider the size of the molecules involved.
3Question 3.
What does Fick's law state about the direction of flux?
- It moves from low to high concentration
- It moves from high to low concentration
- It moves in all directions equally
Show hintHide hint
Think about where substances want to go.
4Question 4.
True or False: Higher viscosity increases the rate of diffusion.
- True
- False
Show hintHide hint
Consider what happens to syrup compared to water.
Question 5.
Describe a real-world pollution incident where diffusion played a key role. Analyze the factors involved and discuss how resistance affected the pollution's spread.
Show hintHide hint
Apply the concepts of flux and resistance to observable phenomena.
Question 6.
Calculate the rate of diffusion for a hypothetical substance given its diffusion coefficient and concentration gradient. Discuss how changes in the concentration gradient affect the rate.
Show hintHide hint
Ensure you reflect on how concentration changes impact this calculation.
