2 cards from this section. Quick, good the night before a test.
Describe Fick's Law in your own words.
Think about how and where diffusion occurs in nature.
What is the role of the diffusion coefficient?
Consider factors that might change this coefficient.
What does Fick's Law describe?
Think about substance movement.
True or False: Higher temperature generally leads to increased diffusion rates.
Check your understanding of molecular motion.
Discuss how Fick’s Law can help in predicting the spread of a pollutant within a lake. Include factors that would be critical in such a prediction.
Reference examples from real environmental assessments to draw connections.
Using Fick's Law, calculate the flux of a substance when the concentration changes from 10 mg/L to 2 mg/L across a distance of 5 meters if the diffusion coefficient is 0.1 m²/s.
Make sure to identify which concentration is higher; direction matters in diffusion outcomes.
