Diffusion is the movement of chemical molecules across a membrane based on differences between concentration gradients on either side of the membrane. Diffusion is particularly used in the transport of salts. Diffusion is the net movement of molecules from a region of high concentration to a region of low concentration, resulting from random thermal molecular motion. Diffusion is a process fundamental to life - no wonder then that it's studied in GCSE biology.

Diffusion Definition 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. Similarly, the medium in which diffusion occurs could also be in one of the three physical states. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Passive diffusion is the movement of molecules across a membrane, such as a cell membrane. The movement does not require energy.

What is an example that describes molecules moving down a concentration gradient? Warm air moving from a radiator to fill up a room Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient. The kinetic energy of the molecules results in random motion, causing diffusion.

Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier. Active transport is the movement of molecules from areas of low Diffusion is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached. The movement of molecules is called Diffusion. Diffusion. Movement of molecules from area of high concentration to areas of low concentration - a random movement. Factors effecting rate of diffusion. -Temperature: Higher temp increases movement.
