Diffusion
This is entropy, the tendency for an ordered system to move to a state of lower energy (every thing evenly spread out). Brownian motion (haphazard random motion of molecules) accounts for the motion.
Difusion in air. Osmosis in water.
When particles diffuse they break apart, down into simpler substances. Diffusion is the net movement of molecules from high to low concentration through random motion. From the particle point of view it just moves about at random (as usual) but the overall effect is for the particles to spread out evenly.
The food coloring will eventually mix with the liquid through the process of diffusion. At the start, all of the dye molecules are close together (so the area that they are in contains a high concentration of dye molecules). As they move around, they eventually move from this area of high concentration to an area of lower concentration (the rest of the water). After this process of diffusion is complete, the dye molecules are evenly distributed thoughout the entire liquid (the concentration is equal everywhere).
Scent is normally based on a fragrance in a spirit type of liquid. The spirit starts to evaperaste in to the surrounding air as molecules and dissipates in the air molecules as they move about the space that encounter
The process is called Diffusion. This is why when you spray air freshener in a room it will eventually fill it.

Diffusion
The process is called diffusion. It is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the natural tendency of particles to spread out and become more evenly distributed.
The movement of molecules down a concentration gradient happens through a process called diffusion. This is when molecules move from an area of high concentration to an area of low concentration, driven by the natural tendency of particles to spread out evenly. This movement continues until the concentration is balanced throughout the system.
When molecules are evenly distributed through a solid, liquid, or gas, we say that the substance is in equilibrium. In a solid, the molecules are tightly packed and vibrate in place. In a liquid or gas, the molecules move freely and randomly.
Cleavage
The movement of matter due to differences in concentration is called diffusion. It is the process by which molecules spread from areas of high concentration to areas of low concentration until equilibrium is reached. This movement is driven by the natural tendency of particles to distribute evenly.
When molecules are evenly distributed through a liquid it is called a homogeneous mixture, or solution. This means that the substances are uniformly spread throughout the liquid and there is no visible distinction between the different components.
Diffusion of molecules arises from the constant random motion of particles due to their kinetic energy. These molecules move from an area of high concentration to an area of low concentration in order to establish equilibrium. This process is driven by the natural tendency of particles to distribute themselves evenly in a given space.
The process that allows raw materials like oxygen to move into the cell for cellular respiration is called diffusion. Oxygen molecules move from an area of higher concentration outside the cell to an area of lower concentration inside the cell through the cell membrane. This passive transport mechanism does not require energy, as it relies on the natural tendency of molecules to spread out evenly. Once inside, oxygen is utilized in the mitochondria to produce energy through cellular respiration.
When two gases are in contact, they will mix and diffuse until they reach an equilibrium where their concentrations are evenly distributed throughout the space. This process occurs due to the random motion of gas molecules and the tendency for molecules to move from regions of high concentration to regions of low concentration until a uniform distribution is achieved.
