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?
Is diffusion an act of active transport?
No, diffusion is not an act of active transport. Diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration, without the input of energy. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
How do you calculate diffusion in a given system?
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.

What does the diffusion of water mean?
The diffusion of water refers to the movement of water molecules from an area of high concentration to an area of low concentration. This process occurs naturally to achieve equilibrium and is important for processes like osmosis in living organisms.
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 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.
