How long does it take for carbon dioxide to disperse?

Question

a. 1yr.

b. 10yrs.

c 100yrs or more

Answer 1

10000000000000

Answer 2

this is an awfully ambiguous question.  where is carbon dioxide dispersing?  is it in a container? room? Atmosphere?

Answer 3

OK, scientifically speaking, the answer should be:

None of the above, since any gas immediately begins to disperse once it it is created or placed into any environment, since all gasses distribute evenly.

I suspect that you may be asking an answer to a rather useless question however.

I think(reading between the lines here) that this has to have some correlation to a rather pathetic school question which there really is no valid answer to.

The proper answer should be immediately!

Although that will not satisfy your misguided teachers or curriculum.

The answer will be whatever BS they told you it is 'supposed' to be in your study.

Answer 4

I think the answer your after is 100 years (ive seen it referred to in reports before), but thats probably based on a big fat assumption by someone as we dont yet fully understand the various sinks. Scientists recently found the deserts are obsorbing co2 more than was ever though, and parts of the sea are acting as huge sinks but no one knows why

Answer 5

It doesn't disperse, but displaces.

Answer 6

According to a article by Robinson and Soon very little:

"Carbon dioxide has a very short residence time in the atmosphere.

Beginning with the 7 to 10-year half-time of CO2 in the atmosphere

estimated by Revelle and Seuss (69), there were 36 estimates of the

atmospheric CO2 half-time based upon experimental measurements

published between 1957 and 1992 (59). These range between 2 and

25 years, with a mean of 7.5, a median of 7.6, and an up per range

average of about 10. Of the 36 values, 33 are 10 years or less. Many of these estimates are from the decrease in atmospheric carbon 14 after cessation of atmospheric nuclear weapons testing, which provides a reliable half-time. There is no experimental evidence

to sup port computer model estimates (73) of a CO2 atmospheric

“lifetime” of 300 years or more."

Answer 7

The martian is right.

Answer 8

Stryder is right - very ambiguous.

Incidentally, eric is talking about residence time, not dispersal time.

If, by dispersal, you mean how long will quantity X of CO2 released into volume Y be homogenously and randomnly distributed throughout Y? Then there are a lot of variables to consider including (but not limited to): Ambient temperature & pressure, mechanism of release, turbulence and constituency of existing gases (if any) in Y, etc...
