Diffusion
Thermal motion is the random movement of particles (atoms or molecules) within a substance due to their kinetic energy. This motion is driven by the temperature of the substance, with higher temperatures leading to increased kinetic energy and faster movement of particles.
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.
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.
Diffusion is the result of particles moving in a constant zigzag motion. This random movement leads to particles spreading out from an area of high concentration to an area of low concentration.
This is diffusion. No energy required, molecules do this just based on random molecular motion. Example: a drop of ink dropped into a beaker of water will "diffuse" until it is as spread out as possible.
The movement of a substance from an area of high concentration to an area of low concentration is known as diffusion. This process occurs due to the random motion of particles, leading to a net movement of particles down their concentration gradient. Diffusion is driven by the principle of entropy, seeking to achieve a state of equilibrium where the concentration of the substance is uniform throughout the system.
They both follow the concentration gradient i.e. require no energy for the process to occur. Diffusion is the movement of particles from an area of higher concentration to lower concentration. See Brownian motion. Osmosis is the movement of WATER particles across a semi-permeable membrane from an area of higher concentration to the lower concentration in the effort to reduce the solute concentration.
The processes of diffusion and Brownian motion provide evidence for the particulate theory of matter. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, showing that particles are in constant motion. Brownian motion is the random movement of particles in a fluid due to collisions with other particles, confirming the existence of particles making up matter.

Brownian motion, also known as random motion, is the natural vibrations of particles that drive diffusion. This movement is caused by the constant collisions of molecules in a fluid, leading to the random motion of particles and their eventual dispersal from regions of higher concentration to regions of lower concentration.
