Question 1.
Define flux in the context of mass transfer.
Show hintHide hint
Think about the flow of substances.
Question 2.
What does Fick’s Law describe?
Show hintHide hint
Recall the direction of substance movement.
3Question 3.
What does flux represent in mass transfer?
- The speed of a fluid
- The mass of a substance
- The rate of transfer per unit area
Show hintHide hint
Think about how we measure flows in pipes or rivers.
4Question 4.
True or False: Higher temperatures decrease the diffusion coefficient.
- True
- False
Show hintHide hint
Reflect on how heat changes movement behavior.
Question 5.
In a river contaminated with a pollutant, using the box model, how would you determine the effectiveness of bioremediation efforts over time based on mass transfer?
Show hintHide hint
Focus on changes in concentration levels and rates over designated time frames.
Question 6.
Analyze a scenario where a change in flow velocity impacts pollutant spread. How might you theoretically describe this using mass transfer equations?
Show hintHide hint
Consider how higher velocities impact diffusion layers at interfaces!
