Observation of an object at rest or stationary would not show molecular motion.
Molecules are constantly in motion. Whether they are free moving, as in a gas, or are vibrating in place, as in a solid object, they still move. an object that has reached the theoretical temperature of absolute zero would have no molecular motion, but absolute zero is purely theoretical and is thereby unattainable.
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.
No, molecular motion actually increases when water is boiling. When water reaches its boiling point, the molecules absorb enough heat energy to break free from the liquid phase and transition into the gaseous phase, leading to increased molecular motion.
The movement of particles due to molecular motion is called diffusion. It is the process by which particles spread out from an area of high concentration to an area of low concentration, driven by the random motion of molecules.
Molecules are not in random motion when a substance is at absolute zero, the lowest possible temperature at which molecular motion ceases. At this point, molecular movement only exists due to the zero-point energy, preventing complete immobilization.
The name of the theory that explains Brown's observation is the kinetic molecular theory of matter. This theory states that all matter is composed of particles (atoms or molecules) that are in constant motion, and explains the behavior of gases, including diffusion, pressure, and temperature.
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).
The solid state has the least molecular motion.

Increased molecular motion leads to higher kinetic energy among the molecules in a substance. This causes the molecules to move more rapidly and collide with each other more frequently. Consequently, temperature and molecular motion are directly related due to the kinetic energy of the molecules.
Molecular motion refers to the movement of molecules in a substance, which is manifested through various forms like translation, rotation, and vibration. This motion is driven by factors such as temperature and energy, and it affects the physical properties and behavior of substances. Understanding molecular motion is crucial in fields like chemistry and physics for explaining phenomena like diffusion and phase transitions.
It is not known and, thanks to Brownian motion, it cannot be known.
