Show hintHide hint
How does a substance interact with water?
3Question 3.

- True
- False
Show hintHide hint
Consider the processes involved.
Question 5.
Consider a scenario where a large oil spill (L-NAPL) occurs in a river. Model the expected diffusion impact over the first week.
Show hintHide hint
Address the concentration gradient in your model.
Question 6.
