Diffusion

“How do substances spread?”
Chemical substances can be found everywhere. However, these objects are almost always never in static position, and will constantly move around. So how can we classify the phenomena of the dispersion of chemicals? Well, after many years of research, Chemists have developed the concept of diffusion. Diffusion is when molecules from a high concentration (dense collection) diffuse into the surrounding environment until an equilibrium state is reached. Diffusion not only happens in fluids but can also occur in solids. Specifically, the atoms in solids are always vibrating, and if there are holes within the lattice, then atoms from neighboring gasses can enter the substance and effect its material properties. An example of this can be seen with piping. If the material of the pipes is not properly designed, then atoms of the transport fluid can merge with the solid material and cause brittleness which will eventually lead to breakdown.
