Do you think the temperature of the room affects the time it takes an odor to get to your nose? 

Yes, I think that the temperature of the room affects the time an odor gets to your nose. First of all, the particles that make up the gas will rise if there is heat(I think) and will go down if it is cold(I think). This means that the heat will take over more of the room with the molecules and that will take over the smell.
