Challenge Problems
Push your limits with challenges.
Question 1
A lake contains a pollutant at an initial concentration of 10 mg/L. If 15% of this concentration evaporates in the first week, what will be the new concentration?
💡 Hint: Calculate 15% of the initial concentration and subtract from it.
Question 2
If the evaporation rate increases due to rising temperatures, how would you model the kinetic energy factor's effect on pollutant concentration in a lake?
💡 Hint: Consider the direct relationships between temperature, evaporation, and concentration levels.
