Diffusion
Particles in a gas or a liquid are constantly moving.
Because of this, the particles will try to spread themselves out evenly throughout the gas or liquid.
If liquid/gas particles are 'bunched together', they will try to spread out and fill the space that they are in.
This is called diffusion.

Diffusion
The movement of particles from a region of high concentration to an area of low concentration.
The particles will do this until they are evenly spread out (although they will still move around).
This is a passive process and does not require any energy!
