Solid particles vibrate while locked in place. As they receive more energy, particles speed increases. Once the particles have enough energy they break apart and slide past each other as a liquid. The particles speed continues to increase as energy is added. Finally, they gain enough energy to break free and move independently as a gas.
The relationship between molecular motion and pressure is described by the kinetic molecular theory, which states that gas pressure results from collisions between gas molecules and the walls of a container. As molecular motion increases—due to higher temperature, for example—the frequency and force of these collisions also increase, leading to higher pressure. Conversely, if molecular motion decreases, the pressure decreases as well. Thus, pressure is directly related to the average kinetic energy of the molecules in a gas.
The increasing range of molecular motion typically occurs in the following order: solid < liquid < gas. In a solid, molecules have the least amount of motion as they are tightly packed and don't move much. In a liquid, molecules have more freedom to move around but are still relatively close together. In a gas, molecules have the highest range of motion as they are far apart and move freely.
Observation of an object at rest or stationary would not show molecular motion.
The process of gas molecules in a container moving in straight lines, colliding with each other and the walls of the container can be explained by the kinetic-molecular theory. This theory describes how the behavior of gas molecules is influenced by their motion and energy.
The kinetic molecular theory for gases does not assume the presence of intermolecular forces between gas particles. It assumes that gas particles are in constant, random motion and that the volume of the gas particles is negligible compared to the volume of the container.
They move around freely!!
Boiling or gas
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.

Rapid Motion does.

As a substance transitions from liquid to gas, the molecular motion increases. In the liquid state, molecules move more freely but are still close together. When the substance becomes a gas, the molecules move even more rapidly and are much farther apart.
As a substance changes from a solid to a liquid, the molecular motion increases as the intermolecular bonds break and the molecules can move past each other more freely. When a substance transitions from a liquid to a gas, the molecular motion increases further as the molecules have enough energy to overcome intermolecular forces entirely and move independently.

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.
Kinetic Molecular Model?? kinetic molecular model,which describes the behavior of solids,liquids and gases,was established based on the kinetic molecular theory. :)) SOURCE?. mah book^^ ♥
The change from a gas to a liquid involves a decrease in molecular motion. In this phase transition, the particles come closer together, reducing their kinetic energy and resulting in a more ordered arrangement.
