What happens to the CFC molecule in the lower atmosphere?
In the lower atmosphere, CFC molecules undergo photolysis when they are exposed to ultraviolet radiation from the sun. This process breaks down the CFC molecule into chlorine atoms, which can then catalyze the destruction of ozone molecules. This contributes to the depletion of the ozone layer.
Why are the effects of the CFC gases ban taking so long to work?
CFC gases have a long atmospheric lifetime, meaning they can persist for many years after being emitted. It takes time for them to break down and be removed from the atmosphere. Additionally, some older equipment and products containing CFCs may still be in use, delaying the full impact of the ban.
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 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 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 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.
Which atoms in the cfc molecule can destroy thousands of ozone molecuels in the upper atmosphere?
Chlorine atoms in CFC molecules can destroy thousands of ozone molecules in the upper atmosphere when they are released due to UV light breaking down the CFC molecules. These chlorine atoms react with ozone molecules, causing them to break apart and reduce the ozone concentration in the atmosphere.
What happens to the CFC molecule in the lower atmosphere?
In the lower atmosphere, CFC molecules undergo photolysis when they are exposed to ultraviolet radiation from the sun. This process breaks down the CFC molecule into chlorine atoms, which can then catalyze the destruction of ozone molecules. This contributes to the depletion of the ozone layer.
Can CFC creates ozone layer?
No CFC's cannot create the ozone and ozone layer. They can only destroy ozone molecules in the atmosphere.
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.
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.
Why are the effects of the CFC gases ban taking so long to work?
CFC gases have a long atmospheric lifetime, meaning they can persist for many years after being emitted. It takes time for them to break down and be removed from the atmosphere. Additionally, some older equipment and products containing CFCs may still be in use, delaying the full impact of the ban.
Which atoms in the CFC molecule can destroy thousands of ozine molecules in the upper atmosphere?
Chlorine atoms in CFC molecules can destroy thousands of ozone molecules in the upper atmosphere. When CFCs break down in the stratosphere due to UV radiation, the chlorine atoms released can catalyze the breakdown of ozone molecules, leading to ozone depletion.
How do chlorofluorocarbon destroy ozone molecules?
CFC's reach atmosphere by westerly's. They deplete ozone in presence of PSC's.
How does CFC reach the stratosphere?
CFCs are released into the atmosphere from human activities like air conditioning and refrigeration. Once in the atmosphere, they are carried up into the stratosphere by wind and air circulation. In the stratosphere, CFCs can remain for many years, allowing them to break down ozone molecules through chemical reactions.
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.
