When the smell in my room seems to be full of flatulence(it wasn't me), what happens with the gases when I open a window? Detail: It is winter and the air outside is cold whereas the air in the room is warm. When I close the window the smell of flatulence comes back nearly right away. What does the process of diffusion look like here?
And would the smell be dispersed faster if I sprayed another odor into the room?
