mass transport theory

Mass transport theory is a scientific concept that explains how substances move from one location to another, typically within fluids like gases or liquids. It evaluates the rates and patterns of this movement, which can occur through processes like diffusion (spreading from high to low concentration), convection (movement due to fluid flow), and advection (transport with the bulk movement of a fluid). Understanding these processes is crucial in fields like chemistry, environmental science, and engineering, as it helps predict how pollutants disperse, how nutrients circulate in ecosystems, and how materials interact in various industrial applications.
