jittering motions of pollen grains as viewed under a microscope
Molecular motion / kinetic energy.
Temperature is just a name for "internal energy of grain / molecular / atomic / nucleon motion". Melting is changing from "grain dominant" motion to "molecular dominant" motion, as the energy released in forming the (usually) more stable grain structure is added back in.
It triggers diffusion because diffusion is the movement of molecules, therefore as soon as the molecules move diffusion begins to do it's job. It will take them from areas of greater concentration to areas of lesser concentration.
All molecular motion stops at absolute zero. This would not stop the passage of time.
they based there conclusion on the evidences
Observation of an object at rest or stationary would not show molecular motion.
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.
They move around freely!!
a measure of molecular motion
It vibrates slightly.

Molecular motion / kinetic energy.
Brownian motion describes the disorder of random molecular motion, which is caused by the collision of molecules in a fluid. This phenomenon was first observed by botanist Robert Brown in 1827.
