diffusion
why can the odor of perfume reach you?
Perfume particles mix with the particles of air. Due to diffusion, the particles of smelly gas are free to move quickly in all directions.
the particles in the perfume grabs one of the molecules as you spray and they keep jumping on each molecule so afters the whole room would smell of it. ----------- Gas diffusion
the diffusion of the perfume molecules in the air.
The phase is called diffusion. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, allowing the perfume particles to spread out and reach your nose even across the room.

a good example of diffusion is when you spray perfume on yourself,it can be smelled from far away. this is because of diffusion,the molecules of the perfume try to travel the areas where they are not present than the areas where they are present in high concentration..
