In diffusion a particles move from areas of ___________ concentration to areas of __________ concentration.
This is due to the random collisions between the particles in the surroundings and the particles being diffused.
Diffusion _____________ happen in solids as the particles are fixed in position.
Diffusion _________ occur in liquids or gases as the particles are free to move.
Diffusion is ___________ in gases as the particle in a gas are moving faster.
If the temperature of a gas or liquid is increased the rate of diffusion is also ______________ as there are more frequent and more forceful collisions.

Select one Ne atom to represent the particle being diffused (this is the small blue dot).
Run the simulation with 10 Ar atoms and estimate/time how long it takes for the blue atom to make it to the other side of the container).
Repeat this for an increasing number of Ar atoms.
As the number of Ar atoms increases the time taken for the Ne atom to diffuse ______________.
As the number of Ar atoms increases the frequency of direction changes for the Ne atom ______________and the distance that the the Ne atom goes before changing direction ______________ .
In this experiment:
The number of Ar atoms is the ________________ variable.
The time taken for the Ne atom to "diffuse" is the ______________ variable.
The volume of the container is a ____________ variable.
