Diffusion
From kinetic theory, matter is made up of particles that are in continuous random motion.
In solids, the particles are at fixed positions and can only vibrate at these fixed positions.
In liquids and gases, the particles are loosely held and are free to move from one region to another randomly. This movement of gas or liquid particles is observed to be from regions of high concentration to a region of low concentration. The process by which particles move from a region of high concentration to a region of low concentration is known as diffusion.
In particular, the scent of a ?ower or perfume experienced by an individual is as a result of the flower scent particles or perfume particles move from a region of high concentration.
Diffusion occurs until the regions have an even concentration of the liquid or gas particles.
The difference in concentration of particles between the region of high concentration and region of low concentration is known as the diffusion gradient/concentration gradient.
