∙ 14y agoThe CFC does not just escape from the vents, but from broken connections, hoses, seals / gaskets, even migrating through solder joints. Most CFC escapes when the car is harvested for its parts. Any CFC takes several months to make it to the upper atmosphere, and it may take a few decades (we hope it is that fast) for the chlorine payload to eventually leave the ozone layer. Not all the CFCs released at Earth's surface make it to the upper atmosphere, but they do serve to increase the partial pressure of CFC, which boosts other molecules higher on average. The only "natural" way to eliminate CFCs from the atmosphere, is to break them down in the "ozone layer". Fluorocarbons (no effect on ozone) will have to go even higher to get the necessary energy.

∙ 13y agoThey stay for a considerable period of time. Some believe that CFC's make their way to the poles and help with the natural thinning of the ozone layer their that occurs naturally each winter for a few months. The layer only has this hole during the winter months and heals when the sun returns.

∙ 11y agoNot all CFCs have the same staying power in the atmosphere. The duration of their existence is measured as a half-fife (the time for half of a release of CFCs to decompose). CFCs' half lives range from 60 to 640 years depending on the compound, the related compounds HFCs have a half life of2 to 250 years. again depending on the compound.

Why are the effects of the CFC gases ban taking so long to work?
This is since there are still cfc molecules in the earth's stratosphere which will remain there for a very long time (considering the amount of cfc's used in aerosols and old refigerators).
What happens to the CFC molecule in the lower atmosphere?
an explosion
How the chlorine atoms are formed in the ozone layer?
CFC's i.e Chloro Fluorocarbon which are released from deodorants, refrigerants are carried upwards towards the atmosphere where in presence of the high energy ultraviolet rays these break down into molecules of chlorine and fluorine molecules which further deplete ozone.
How does chlorofluorocarbon rise to the stratosphere?
CFC is lighter than air just like hot air. Once freed, it rises readily to the upper atmosphere at the level of the ozone layer where it can react with the extra atom of oxygen in the ozone.
How long does it take for chlorofluorocarbons to reach the stratosphere?
Chlorofluorocarbons, also called CFC, go into the stratosphere. Air is lighter than the CFC and they can take about 2 to 5 years to travel in the stratosphere.
How long do cfc's remain in the ozone before breakdown?
CFC's remain for very long before breakdown. They can destroy a total of one hundred thousand ozone molecules before breakdown.
Why are the effects of the CFC gases ban taking so long to work?
This is since there are still cfc molecules in the earth's stratosphere which will remain there for a very long time (considering the amount of cfc's used in aerosols and old refigerators).
Which atoms in the CFC molecule can destroy thousands of ozone molecules in upper atmosphere?
The CFC molecules are man made chemicals for refrigeration. The molecules on reaction release 2 gases. These gases are Chlorine and Fluorine.
Can CFC creates ozone layer?
No CFC's cannot create the ozone and ozone layer. They can only destroy ozone molecules in the atmosphere.
What do chemicals released into the atmosphere break ozone down into to?
CFC's are released into atmosphere. They break the ozone into oxygen molecules.
What atoms in the CFC molecule can destroy thousands of ozone molecules in the upper atmosphere?
The CFC's molecules are ODS. They react with ozone to deplete it. The Chlorine and Fluorine are main atoms.
How long is the life spent of CFC in greenhouse gas?
CFC's stay for a long time. They deplete 100,000 molecules of ozone each.
How do chlorofluorocarbon destroy ozone molecules?
CFC's reach atmosphere by westerly's. They deplete ozone in presence of PSC's.
How many CFC molecules are produced in 2 hours?
CFC molecules are fatal for ozone. large amount of CFC molecules are produced in 2 hours.
CAN sunlight striking CFC molecules cause chlorine to be released?
Yes! Once cfc's are released into the atmosphere the travel into the statosphere where they linger for hundreds of years & under the influance of sun light a chlorine atom is released from the cfc molecule.
Can sunlight striking CFC molecules can cause Chlorine to be released?
Yes! Once cfc's are released into the atmosphere the travel into the statosphere where they linger for hundreds of years & under the influance of sun light a chlorine atom is released from the cfc molecule.
If cfc's stay in the atmosphere so long why has the hole in the ozone closed after only 20 years of none use of cfc's?
The ozone hole is not yet closed. And ban on CFC's has been long enough now.
