Question 1.
What does Fick's Law describe?
Show hintHide hint
Recall the equation involving flux.
Question 2.
Name one factor that affects diffusion.
Show hintHide hint
Think about the medium the substance is moving through.
3Question 3.
What is the primary principle described by Fick's Law?
- Flux proportional to temperature
- Flux proportional to concentration gradient
- Flux independent of concentration
Show hintHide hint
Think about how substances tend to move.
4Question 4.
True or False: Lower density of a medium increases resistance to diffusion.
- True
- False
Show hintHide hint
Consider how substances move through dense vs less dense mediums.
Question 5.
Calculate the time it takes for a pollutant to diffuse through a sediment layer given a specific diffusion coefficient.
Show hintHide hint
Remember, more concentration difference means faster flux.
Question 6.
Discuss how a change in temperature affects pollutant behavior in water using the concepts learned.
Show hintHide hint
Relate it to kinetic energy focusing on particle movement.
