SUMMARY
Fick's Second Law of Diffusion describes how concentration changes over time, specifically through the relationship between concentration gradients and time. The discussion clarifies that deriving the second law from the first law involves not only taking the partial derivative with respect to spatial variable x but also applying the principle of conservation of mass. This foundational concept is crucial for understanding diffusion processes in various scientific fields.
