WebDiffusion is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in … Web2 days ago · We investigate diffusion-driven flows in a parallel-plate channel domain with linear density stratification, which arise from the combined influence of gravity and diffusion in density-stratified fluids.
WebMar 26, 2024 · Diffusion rates are dependent on molecular sizes because larger molecules diffuse slower than smaller molecules. The sizes of the particles involved in the diffusion are important because they closely relate to the concepts of heat and energy in the context of diffusion. It takes more energy and heat to move a larger object than a smaller one, …
