Answer:
Volatile perfume molecules leave the bottle and move randomly through the room. When the concentration of perfume molecules becomes sufficiently large near your nose, your olfactory system sends a message to your brain that you smell perfume. Such diffusion is an excellent example of spreading phenomena.
