Jul 29, 2019 · Diffusion is the movement of a fluid from an area of higher concentration to an area of lower concentration. Learn more about this chemistry concept.
A process in which the substance moves through a semipermeable membrane or in a solution without any help from transport proteins. For example, bacteria deliver small nutrients, water and oxygen into the cytoplasm through simple diffusion.
Jul 2, 2024 · diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
Nov 21, 2023 · Diffusion is defined as the movement of atoms, ions, and molecules from a region of high concentration to a region of low concentration, or ‘down their concentration gradient ’. The word ‘diffusion’ is derived from the Latin word, ‘diffundere’, meaning ‘to spread out’. Diffusion. What Causes Diffusion and What Happens During the Process.
Apr 4, 2022 · Diffusion is the movement of particles from higher concentration to lower concentration. Diffusion continues until equilibrium is reached. At equilibrium, concentration is the same throughout the sample. Familiar examples of diffusion are the transport of perfume when it is sprayed in a room or the movement of food coloring in a glass of water.
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 Gibbs free energy or chemical potential.
Feb 13, 2023 · Diffusion can be described as the random movement of particles through space, usually due to a concentration gradient. Diffusion is a spontaneous process and is a result of the random thermal motions between two particles. The diffusion coefficient (\(D\)) can be solved for with Fick’s laws of diffusion, which are broken up into two laws.
Apr 10, 2019 · Diffusion is the tendency of molecules to spread out in order to occupy an available space. Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane.
Diffusion is the process by which particles of one substance spread out through the particles of another substance. Diffusion is how smells spread out through the...
Aug 13, 2021 · Diffusion is the gradual mixing of gases to form a sample of uniform composition even in the absence of mechanical agitation. In contrast, effusion is the escape of a gas from a container through a tiny opening into an evacuated space.
