Where there are two (or more) substances in contact, diffusion happens as particles of one substance move from an area where there are a lot of those particles to an area where there are fewer of those particles. The process can happen in the gas, liquid and solid phase.
Note, diffusion is driven by random movement of the particles not by mechanical mixing, the phase of the system will therefore largely determine the rate of diffusion.
The term is also used in a more abstract manner to describe spreading of something more widely. The movement of a substance from a region of high concentration into a region of low concentration is called diffusion.
What else can I help you with?
What is the relation between apparent diffusion coefficient and mean diffusivity on DTI?
Apparent diffusion coefficient (ADC) is a measure of water diffusion in all directions, while mean diffusivity is a measure of the average diffusion within a voxel. ADC includes the effects of both isotropic and anisotropic diffusion, whereas mean diffusivity reflects the overall diffusion within the voxel. In DTI, ADC is calculated as the average of the three eigenvalues, which correspond to the three principal diffusion directions and contribute to mean diffusivity.
What role does diffusion play in cellular respiration?
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
What does the statement diffusion goes from the higher concentration side to the lower concentration side mean?
That partial pressures are the driving force in diffusion.
What is diffusion a natural movement of molecules from?
in the normal diffusion the substance move from the area of greater concentration to that of lower concentration. .... but i never know what do we mean be "faciliated" plz specify
Diffusion of AIDS is an example of which type of diffusion?
Diffusion of AIDS is an example of contagious diffusion, where the disease spreads through direct or indirect contact between individuals.

What will happen if the net diffusion stopped?
what do you mean
What do you mean by global diffusion of nuclear weapons?
proliferation
What does of fluid diffusion mean?
Hahahahaa i was also looking for that answer....
What role does diffusion play in cellular respiration?
well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis
What does cultural diffusion mean in history?
When two cultures blend.
What is definition of diffusion current?
The diffusion current in a metal-semiconductor diode is derived based on the assumption that the depletion layer is large compared to the mean free path, so that the concepts of drift and diffusion are valid.
What is the relationship between the root mean square distance and diffusion in a system?
The root mean square distance is a measure of how far particles move on average in a system. In diffusion, particles move randomly and spread out over time. The root mean square distance increases as diffusion occurs, showing a direct relationship between the two.
What are the types of cultural diffusion?
contagious diffusion, relocation diffusion, expansion diffusion, stimulus diffusion, hierarchical diffusion.
The spreading out of a substance from an area of high concentration to an area of low concentration is called .?
diffusion
How does diffusion effect cells?
I think you mean how does it affect cells but im not sure
What does it mean for a cell to be equilibrium?
It is after diffusion when the number of molecules is equal in all areas.
