stoffübergang
Stoffübergang, also known as mass transfer, refers to the net movement of a chemical species from one location to another. This movement can occur through various mechanisms, including diffusion, convection, and phase change. In diffusion, the net movement is driven by concentration gradients, where substances move from areas of high concentration to areas of low concentration. Convection involves the bulk movement of a fluid, carrying dissolved or suspended substances along with it. Phase change, such as evaporation or dissolution, also leads to stoffübergang as a substance moves between different physical states.
The principles of stoffübergang are fundamental in many scientific and engineering disciplines. In chemical engineering, it
The rate of stoffübergang is influenced by factors such as the concentration difference, the surface area available
