What is a box model?
Show hintHide hint
Think about how models help simplify complex systems.
Question 2.
Explain what it means for a system to be well-mixed.
Show hintHide hint
Consider whether all parts of a container have the same mixture.
3Question 3.
What is a key limitation of box models?
- They assume uniform concentration
- They require complex calculations
- They are only applicable in the lab
Show hintHide hint
Think about the assumptions made in modeling.
4Question 4.
True or False: Box models are effective for all environmental systems.
- True
- False
Show hintHide hint
Consider conditions where this model may not apply.
Question 5.
Given a lake with a 1000L capacity, where water evaporates at 10L/day and receives an inflow of 5L/day with a pollutant concentration of 1mg/L, calculate the concentration after one day.
Show hintHide hint
Calculate the total pollutants added and lost through evaporation.
Question 6.
Critically analyze a scenario where a box model fails to predict pollutant transport in a river with tributary contributions and variable flow rates, providing examples.
Show hintHide hint
Think about external inputs that vary throughout different seasons.
