Question 1.
What does mass transfer refer to?
Show hintHide hint
Think about how different phases like liquid, solid, and gas interact.
Question 2.
What is a dispersion model?
Show hintHide hint
Focus on its role in environmental science.
3Question 3.
What is the primary factor driving molecular diffusion?
- Temperature
- Concentration gradient
- Pressure
Show hintHide hint
Think about the natural tendency of substances to disperse.
4Question 4.
True or False: Oil will always sink in water.
- True
- False
Show hintHide hint
Consider how density factors into this scenario.
Question 5.
An oil spill of 100 liters occurs in a river. Calculate the potential impact over 48 hours considering evaporation and dissolution rates if 5% evaporates and 10% dissolves. How would this affect surrounding ecosystems?
Show hintHide hint
Assess how immediate removal of 15 liters might change the ecosystem.
Question 6.
Describe how a chemical with a high diffusion coefficient would behave in a body of water compared to one with a low diffusion coefficient. What implications does this have for pollution management?
Show hintHide hint
Link diffusion behaviors to response times in pollution scenarios.
