During freezing, the movement of particles slows down significantly as the temperature decreases. In a liquid state, particles are relatively close together but can move freely and slide past one another. As the liquid cools, the kinetic energy of the particles decreases, causing them to lose their ability to move freely and begin to arrange themselves into a more orderly, fixed structure, forming a solid. This transition results in a solid state where the particles vibrate in place rather than moving freely.

You can tell if the particles in a cup of water are moving faster or slower by observing the temperature of the water. In general, higher temperatures indicate faster particle movement, while lower temperatures indicate slower particle movement. Additionally, you can observe changes in the physical state of the water, such as boiling or freezing, which can also indicate changes in particle movement.
Usually the solid phase, but some substances, importantly water, are exceptions because the liquid near the freezing point has shorter inter-particle distances than the solid near the freezing point.
freezing
A solution of glucose in water has a freezing point that is lower than that of pure water due to the presence of solute particles, which disrupt the formation of ice. This phenomenon is known as freezing point depression. The extent of the freezing point depression depends on the concentration of glucose in the solution, as more solute particles lead to a greater decrease in the freezing point.
The movement of particles decrease as temperature decreases, and vice versa. Therefore, they will decrease while freezing.

The movement of particles in a hard stick of butter are solid. Their not moving. While the movement of particles in a melted sick of butter are liquid. They are moving.
The depression of the freezing point is dependent on the concentration of solute particles in a solution. More solute particles lead to a greater depression of the freezing point.

The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.
