Question 1

What role do mass transfer coefficients play in environmental modeling?

  • They estimate the area under curves
  • They indicate rates of mass transfer between phases
  • They measure temperature changes

💡 Hint: Think about what factors influence how substances mix.

Question 2

True or False: Steady-State conditions imply that concentrations do not change over time.

  • True
  • False

💡 Hint: Recall the definition we discussed in class.

Challenge Problems

Push your limits with challenges.

Question 1

A chemical spill occurs on a lake. Given the mass transfer coefficients, predict the concentration drop over the first hour. Consider water temperature changes during this time.

💡 Hint: Pay attention to how temperature affects diffusion rates.

Question 2

During a forest fire, pollutants are released into the air. How would you set up a model to calculate concentrations downwind over time? What variables would you consider?

💡 Hint: Use the knowledge of dispersion models to frame your approach.
