Gases and liquids are called fluids.Due to the kinetic energy of the atoms/molecules of the fluids they vibrate hence result in a contant mixing or motion of the molecules.

diffusion
The solid state has the least molecular motion.
The molecular motion in a gas is at its minimum possible at absolute zero temperature. At this temperature, the molecules have almost zero kinetic energy, causing them to come to a stop and exhibit minimal motion.
entropy
All molecules are in constant motion. Molecules of a liquid have more freedom of movement than those in a solid. Molecules in a gas have the greatest degree of motion. Heat, temperature and the motion of molecules are all related. Temperature is a measure of the average kinetic energy of the molecules in a material. Heat is the energy transferred between materials that have different temperatures. Increasing the temperature increases the translational motion of molecules Energy is related to temperature by the relationship: E= kT
When water goes solid (freezes), the molecules get "locked" together to form the solid phase. These molecules can't move around like they can in liquid water because they are interconnected and immobile within the lattice. Most solids exhibit the property of atomic or molecular immobility, though is it is possible for some materials to diffuse into or out of a solid structure.
In the dissolving process, the solute particles break apart and disperse into the solvent due to the random motion of molecules. This motion causes collisions between solute and solvent molecules, leading to a gradual mixing at the molecular level until the solute is evenly distributed throughout the solvent.
This is known as vapor pressure. It is influenced by factors like temperature, intermolecular forces, and surface area. Higher temperature and weaker intermolecular forces increase the vapor pressure of a liquid.
the motion of the molecules would slow down
The solid state has the least molecular motion.
As temperature of a solid is increased, molecular motion increases.Since, temperature of a solid is directly proportional to average vibrational kinetic energy of molecules of a solid, therefore, energy of a solid increases with an increase in temperature. So, it demonstrates that molecular motion is directly proportional to energy i.e. the higher the energy of solid, the higher is the molecular motion.
Liquid water molecules exhibit a greater amount of motion than ice molecules.
Molecular motion is less constrained in liquid than in solid and is less constrained in gas than in liquid.
It is not known and, thanks to Brownian motion, it cannot be known.

No, molecular motion does not stop when diffusion stops. Molecular motion refers to the movement of molecules within a substance, which continues even when there is no net movement of molecules from one region to another (diffusion).
