Why can people on one side of a room smell the scent of an air freshener sprayed on the opposite side?

Explanation:

what i would think is when u spray your air freshener it sprays molecules of that freshener the molecules dont just spray and go down there it spreads around the room and some of those molecules also enter ones nose and that is why he smells the freshener

i hope this is helps

b) mutualism

hope this : )
