Meanwhile, the ocean, which acts as a natural sink for carbon dioxide, is losing its ability to absorb emissions.
“By leaving the oil in the ground, we avoid releasing 400 million tons of carbon dioxide into the atmosphere,” says Baki.
These pollutants have life spans of just a few weeks to a decade—much shorter than that of carbon dioxide.
With the Dräger, exhaled breath passes through a chemical filter that removes the carbon dioxide and replenishes the oxygen.
Speaker of the House John Boehner pointed out that the idea that carbon dioxide is “harmful to the environment is almost comical.”
We therefore find oxygen, nitrogen, water vapour, and carbon dioxide remaining as permanent components of our air.
Saturate the residue, when cold, with carbon dioxide and redistil.
We have already seen that the amount of carbon dioxide gas in the atmosphere has a decided climatic importance.
He there amused himself with experiments on carbon dioxide (fixed air).
Transfer block to plate of freezing microtome and freeze with carbon dioxide vapour.
carbon dioxide n.
A colorless, odorless, incombustible gas formed during respiration, combustion, and organic decomposition and used in inert atmospheres, fire extinguishers, and aerosols.
|carbon dioxide |
A colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. It is breathed out of an animal's lungs during respiration, is produced by the decay of organic matter, and is used by plants in photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. Chemical formula: CO2.
Note: Carbon dioxide is normally found as a gas that is breathed out by animals and absorbed by green plants. The plants, in turn, return oxygen to the atmosphere. (See carbon cycle and respiration.)
Note: Carbon dioxide is also given off in the burning of fossil fuels (see greenhouse effect).
