Challenge Problems
Push your limits with advanced challenges
A warehouse has two chambers, one filled with air and the other with helium. If a small hole connects the two, discuss the rate of diffusion for both gases when released into the chamber.
💡 Hint: Consider the molecular weights of both gases.
In a scenario where a pollutant in water is subjected to increased temperature and viscosity, predict its diffusion behavior and justify your reasoning.
💡 Hint: Focus on how both factors interact with each other.
