diffuusi
Diffuusi is a term used in Finnish to describe diffusion, the passive spread of particles from regions of higher concentration to regions of lower concentration due to random thermal motion. In scientific contexts, diffusion is formalized by Fick’s laws and the diffusion equation. The first law states that the diffusive flux is proportional to the negative concentration gradient; the second law describes how concentration evolves over time, enabling modeling of diffusion in gases, liquids, and solids.
Diffusion can occur without bulk movement, but it is influenced by temperature, medium properties, and the size
Biological and technological relevance is broad. In biology, diffusion drives gas exchange, nutrient uptake, and the
