Diffusion is a property of substances in water; substances in water tend to move from an area of high concentration to an area of low concentration. Blood flows by one side of a semi-permeable membrane, and a dialysate, or special dialysis fluid, flows by the opposite side. See more Diffusion 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 See more "Bulk flow" is the movement/flow of an entire body due to a pressure gradient (for example, water coming out of a tap). "Diffusion" is the gradual movement/dispersion … See more In the scope of time, diffusion in solids was used long before the theory of diffusion was created. For example, Pliny the Elder had previously described the cementation process, which produces steel from the element iron (Fe) through carbon diffusion. … See more Diffusion coefficient in kinetic theory of gases The diffusion coefficient $${\displaystyle D}$$ is the coefficient in the Fick's first law $${\displaystyle J=-D\,\partial n/\partial x}$$, where J is the diffusion flux (amount of substance) … See more The concept of diffusion is widely used in: physics (particle diffusion), chemistry, biology, sociology, economics, and finance (diffusion of people, ideas and of price values). However, in each case the substance or collection undergoing diffusion is … See more Diffusion flux Each model of diffusion expresses the diffusion flux with the use of concentrations, … See more One common misconception is that individual atoms, ions or molecules move randomly, which they do not. In the animation on the … See more WebThis movement of water towards the high solute side is osmosis, and is technically due to pressure. (This pressure arises from the solutes binding to some of the water molecules so the solute side actually has less unbound water molecules than the solute free side which causes the pressure flow).

WebOxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood carbon dioxide moves... WebSep 15, 2024 · Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis. WebFurthermore, osmosis requires a semi-permeable membrane, while diffusion does not. The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food colouring is added to a glass of water, where eventually, the entire water content becomes coloured.
