it start melting again
The motion of particles that occurs once a substance has completely melted is called fluid motion. In the fluid state, the particles move freely and do not have a fixed shape or volume.
The erratic motion seen in dust particles suspended in water is called Brownian motion. This motion is caused by the random collision of water molecules with the dust particles, leading to their continuous and irregular movement.
are small, point-like particles that are in constant random motion, and have perfectly elastic collisions with each other and the container walls. Additionally, they have negligible volume compared to the volume of the container in which they are enclosed.
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.
When particles reach their melting point, they absorb enough energy to transition from a solid to a liquid state while maintaining their molecular structure. During melting, the particles gain kinetic energy, causing them to vibrate more rapidly and move further apart, which leads to the solid substance turning into a liquid.
As a block of ice finishes melting, the particles gain enough energy to break the bonds holding them in place. This increased energy causes the particles to move more freely, transitioning from a solid to a liquid state.
When a substance finishes melting, the particles have gained enough kinetic energy to break free from their fixed positions in the solid structure and move more freely as a liquid. The particles will continue to move and flow past one another in a random pattern, which is characteristic of a liquid state.

They can flow around since they're not as tightly packed anymore.
The particles are moving rapidly
The particles are tightly packed so they vibrate.
Brownian motion
Brownian motion is the random moving and mixing of particles.
Smooth lubricated surfaces.
Particles within are limited to vibrational motion, unlike the particles which make up liquids which can have vibrational & translational motion, and gaseous particles which have vibrational, translational and rotational motion.
