  • Diffusion | Definition Examples | Britannica
    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
  • Diffusion - Definition, Examples and Types | Biology Dictionary
    Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration The material that diffuses could be a solid, liquid or gas
  • Diffusion: Definition and How Does it Occur (with Diagram) - Science Facts
    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 – Definition, Causes, Significance, Examples
    Diffusion is a fundamental process involving the movement of particles, such as atoms, ions, or molecules, from an area of higher concentration to one of lower concentration This movement continues until the concentration is uniform throughout the medium, reaching equilibrium
  • Diffusion Definition - BYJUS
    “Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient ” Read on to explore what is diffusion and the different types of diffusion
  • Diffusion - Gas | Thermodynamics - PhET Interactive Simulations
    Mix two gases to explore diffusion! Experiment with concentration, temperature, mass, and radius and determine how these factors affect the rate of diffusion
  • Diffusion - Simple - Facilitated - TeachMePhysiology
    Diffusion is the movement of a molecule down a concentration gradient, from an area of its high concentration to an area of its low concentration This process is passive, i e it requires no input of additional energy; the concentration gradient alone is enough to drive the process
  • What Is Biological Diffusion and How Does It Work?
    Biological diffusion is the movement of substances from an area of higher concentration to one of lower concentration This process is a type of passive transport, meaning the cell does not need to expend any metabolic energy The energy for diffusion comes from the natural, random movement of the molecules themselves
  • Diffusion - Definition, Examples, Types, Factors effecting Causes
    Diffusion stands out as a core principle in biology, crucial for grasping how molecules move within and between cells This process naturally enables particles to migrate from areas of high concentration to those of low concentration, leading to an even distribution
  • Diffusion - Definition, Types, Causes, Factors, Examples Significance
    Learn about the types of diffusion, including simple and facilitated diffusion, and discover the factors affecting diffusion rates Understand real-life examples of diffusion, its causes, and its critical significance in biological systems, such as gas exchange and nutrient transport
