Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does mass balance involve in pollution modeling?
- Rate in = Rate out
- Accumulation = Rate + Reactions
- Zero emissions
💡 Hint: Think of it as a balance scale.
Question 2
True or False: Steady state conditions can still occur in unsteady environments.
- True
- False
💡 Hint: Consider the meaning of 'steady' versus 'unsteady'.

Challenge Problems
Push your limits with challenges.
Question 1
A factory releases a pollutant at a constant rate. Over time, how would you expect the concentration at a monitoring station to behave? Discuss conditions that would validate your steady state assumptions.
💡 Hint: Reflect on what changes can influence pollutant transport.
Question 2
Given a pollutant's rate of flow, derive how the concentration will behave if the emissions suddenly increase by 50%. What does this imply about steady state?
💡 Hint: Consider what happens to balance when sources increase suddenly.
