Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. It is driven by the random motion of molecules and does not require energy input. Diffusion is essential for processes such as gas exchange in the lungs and nutrient uptake in cells.
Diffusion in a system can be calculated using Fick's law of diffusion, which states that the rate of diffusion is proportional to the concentration gradient. The formula for calculating diffusion is D (C2 - C1) / (X2 - X1), where D is the diffusion coefficient, C is the concentration, and X is the distance.

Diffusion is the process that spreads substances through a gas or liquid. It involves the movement of particles from an area of high concentration to an area of low concentration until they reach a state of equilibrium.
A capillary has a very narrow lumn and very thin wall. These features maximize diffusion of nutrients, wastes, and oxygen.
diffusion is.... - the transmission of elements or features of one culture to another - act of diffusing; state of being diffused - prolixity of speech or writing; discursiveness
Large surface area Thin- Short distance for diffusion
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
diffusion
Language diffusion refers to the spread of a language across different regions or communities through contact and communication with speakers of other languages. This can happen through migration, conquest, trade, or other forms of cultural exchange, leading to the adoption of certain linguistic features by other groups.
simple diffusion, osmosis and facilitated diffusion.
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Diffusion is the process of spreading new ideas from culture to culture. Examples of diffusion include the use of cars and the smelting of iron. There are five main types of diffusion they are: Expansion diffusion, Relocation diffusion, Hierarchal diffusion, Congious diffusion and Stimulus diffusion.
Have a large surface area relative to the volume of the organism.They are thin, so have a short diffusion pathway.They have a moist surface where gases can dissolve first before they diffuse in our out.They are able to maintain the diffusion gradient down which the gases can diffuse.
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.
