The movement of molecules from an area of high concentration to an area of lower concentration is called diffusion
In physics and chemistry, diffusion is the thermal movement of all molecules (liquid or gas) from a medium of lower concentration to one of higher concentration, at temperatures above absolute zero, without the generation of additional energy.
The rate of this movement depends on temperature, fluid viscosity and particle size. Once the concentrations are equal, the molecules continue to move, but the process of molecular diffusion has ceased, meaning that an equilibrium has been established, which is called dynamic equilibrium.
What are molecules?
It is the union of two or more atoms by chemical bonds, conserving the physical and chemical properties of that substance.
For example: the water molecule is H2O.
