Detailed explanation-1: -Diffusion is the process of spreading of the gaseous molecule according to their kinetic energy. In this process, particles move from an area of high concentration to an area of low concentration. If the perfume is sprayed in one corner of a room, it will be smelt soon after in the opposite corner.

Detailed explanation-2: -Air fresheners introduce fragrance into the air of interior spaces either as droplets which transition to vapor, or as the molecules of fragrance ingredients directly evaporating from a source. Fragrance diffuses into the air to mask other odors or to introduce a specific odor.

Detailed explanation-3: -Diffusion is the movement of particles from a higher concentration to a lower concentration. That’s why, when you spray perfume in the corner of a room, you will eventually smell it on the other side of the room. The perfume molecules are diffusing through the air molecules, which allows the scent to spread.

Detailed explanation-4: -When you spray air freshener and the scent spreads from a tight space to fill a larger one, that’s diffusion. In science, diffusion is a physical process of atoms or molecules moving apart within a gas or liquid. You can also use the word diffusion to describe the spreading of information.

Detailed explanation-5: -This is diffusion in action! When you spray the air freshener, the concentration of the particles in that corner of the room is incredibly high whereas the concentration of particles in the rest of the air is low. The difference in these concentrations is called a gradient.
