What are non examples of filtration?

Answer 1

Non-examples of filtration include processes that do not separate particles based on size or physical properties. For instance, diffusion, where molecules move from an area of high concentration to low concentration, does not involve filtering. Similarly, mixing substances like sugar in water or dissolving salt in a solution does not constitute filtration, as these processes involve uniform solutions rather than separation. Additionally, sedimentation, which relies on gravity to settle particles rather than a physical barrier, is also not considered filtration.
