Web1 Chapter 5 Chapter 5: Diffusion Diffusion: the movement of particles in a solid from an area of high concentration to an area of low concentration, resulting in the uniform distribution of the substance Diffusion is process which is NOT due to the action of a force, but a result of the random movements of atoms (statistical problem)1. Diffusivity and 2 … WebMay 26, 2024 · Simple diffusion definition. Simple diffusion is a type of passive transport which, as the name suggests, is simply the movement of solute which occurs when its electrochemical potentials on the two sides of a permeable barrier are different. While in other science disciplines like chemistry, diffusion refers to “spreading out” of molecules ...

WebIsotonic solution. The prefix, iso, refers to things that are the same. It has the same concentration of solute, and so you have no net inflow. Hypotonic solution, you have water molecules going into the cell, the cell expanding, kind of like a filling balloon. Isotonic solution, no net flow. WebWhen the molecules of a solute diffuse through a medium containing large colloidal particles, which absorb the diffusing molecules, the latter are transported in the … rpa tools for recording tasks
