I would guess that you are referring to Brownian motion. When a fine dust is spread on the surface of water you can observe the motion of the dust particles through a microscope as they are struck by water molecules.

The motion of particles is accelerated.
are in random, constant, straight-line motion

They can flow around since they're not as tightly packed anymore.

The particles are tightly packed so they vibrate.
The particles are moving rapidly

Brownian motion
The motion of particles is accelerated.
Brownian motion is the random moving and mixing of particles.

Particles absorb energy when boiling (vapourising), melting and subliming. Particles release energy when freezing and condensing.
