diffusion
Diffusion is the mixing of a substance with another substance due to the motion of its particles. The smell of perfume spreading over a room is an example of diffusion. @fragrancesim
why can the odor of perfume reach you?
spraying perfume is one such example! .......when spraying perfume,the scent of the perfume spread around the area!
the diffusion of the perfume molecules in the air.
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..
