Question 1.
What is mass transfer?
Show hintHide hint
Think about how substances move in nature.
Question 2.
Define molecular diffusion.
Show hintHide hint
Consider how food coloring spreads in water.
3Question 3.
What does bulk flow refer to?
- A slow process of diffusion
- Movement of solutes by fluid motion
- Random movement of molecules
Show hintHide hint
Consider how rivers transport materials.
4Question 4.
True or False: In deep lakes, diffusion can be negligible.
- True
- False
Show hintHide hint
Think about the effects of temperature and layering.
Question 5.
A thick oil spill is observed in a river. Discuss how molecular diffusion and bulk flow contribute to the transport of the oil. How might temperature changes affect this situation?
Show hintHide hint
Consider how viscosity affects movement.
Question 6.
Analyze how pollutants might move from an agricultural field into the groundwater during heavy rain. What transport mechanisms are at play?
Show hintHide hint
Think about both surface runoff and subsurface movement.
