Why are home carbon monoxide detectors placed near the ceiling when CO is denser than air? - carbon monoxide in the home
Because it is heavier than air, it forms a layer on the floor. Would it make sense for which of the detectors to be low on the wall?

Carbon Monoxide In The Home Why Are Home Carbon Monoxide Detectors Placed Near The Ceiling When CO Is Denser Than Air?

CO has a molecular weight of 12 +16 = 28
The air is with "The average molecular weight of" 29, so it is slightly heavier than mixed CO
Since carbon monoxide is usually produced by the combustion / The poor combustion, heat really the cause of convection in the room, even if the CO was slightly heavier than air, the first increase the current convection.
Because mixed in a normal room, the CO enough to measure all that is the density of CO is very close to the density of normal air (see ref wiki).
Because it is gas, there are large spaces between the molecules, so that the position of the gas molecules have little effect on other gases in the chamber.
Thus, the carbon monoxide will be spread evenly throughout the room, regardless of other gases are present. It forms a layer on the floor or elsewhere, if the temperature is uniform ..
Otherwise you would a nitrogen blanket and the layer of oxygen in each room
Is denser than air, however, whether the thing just fell to the ground - how can you be transferable to humans?
If the concentration is high will be distributed before the event and if there is a defective boiler information technology being responsible keep going in the room.
That is what detects CO2 are useful, if not higher, but moderate.
, The in the air and falls.
see whether it can affect you, before it falls.
That is my guess.
A: Do not fall away if you are a high concentration of moving into the room.
B. If you just fell hamrfull wouldnt be to humans - if it happens, so that when it reached a source that he has a movement, or the amount of people.
C. Well, first discovered at chest or head office level, before it falls naturally.
:)
It is appropriately furnished.
In the event of fire, hot air with CO, CO2, O2, N2, etc., the impact of the detector. To raise the temperature of the gas, which is not usual detectors near the earth's surface.
