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.
