Diffusion

Diffusion 

is the movement of particles from an area of high concentration to an area of low concentration. 

For this to occur the particles must be able to move so this occurs only in gases liquids and does not occur in solids because particles have no gaps in between them enough for the diffusion to occur.

Examples for Diffusion

Solid particles Diffusing in Liquid particles

When small solid pieces of solid iodine or potassium manganate(VII) are dissolved in water 

the solid particles diffuse in between the water particles and cause the solution 

to be colored with the iodine color

Examples for Diffusion

Solid particles Diffusing in Gas particles

When you are throwing some small stones in the air , the solid particles of stones

diffuses in between the air gas particles

Examples for Diffusion

Gas particles Diffusing in Liquid particles

The particles of Carbon dioxide gas diffusing in water of a Carbonated drink is 

a perfected example.

Examples for Diffusion

Gas particles Diffusing in another Gas particles

An example is the diffusion of bromine gas particles through air particles

Examples for Diffusion

Liquid  particles Diffusing in Gas particles

Drops in rain falling in between air particles

Examples for Diffusion

Liquid  particles Diffusing in another liquid particles

that what happens when you mix liquids together

In all those examples, particles mix by colliding with each other and bouncing off in all directions. This mixing process is called diffusion. The overall result is the flow of particles from where they are more concentrated to where they are less concentrated, until they are evenly spread out.
