And, is it lighter or heavier than air?  Which means, does it rise or fall when produced?
Since the molecular weights of gases differ, what makes them move is convection.  If a gas is released because of combustion, it would tend to rise due to its heat.
CARBON MONOXIDE HAS NEARLY THE DENSITY OF AIR.  ... more
