CFCs break down in the upper atmosphere due to UV light from the sun, forming chlorine radicals (chlorine paricles that will react with just about anything). These will collide with ozone, which is a chemical found in the stratosphere that absorbs harmful solar rays, breaking it down into oxygen.
This process destroys the naural defenses the earth has against damaging levels of solar radiation. Without ozone, cancers and blindness would affect almost every living creature on earth.
This is a problem as we were unaware before of the CFC damage. They cause hole in ozone.
CFC's are used in aerosol cans. They are used as sprays.
CFC's are used in aerosol sprays. They cause ozone depletion.
Yes, CFC's are used in sprays. They are used in aerosols too.
The ozone destroying gas is CFC. They are used in AC's, Deodorants, Aerosol sprays etc.
Further damage of ozone can be reduced. This can be done by banning the use of CFCs. Ban on CFCs can help it. Furthermore planting more trees would help to the cause. Humans can stop ozone depletion. They can stop this by curbing use of CFCs. Do not use aerosol sprays, as they contain the chlorofluorocarbons that destroy the ozone layer. Some refrigerators also contain CFCs, so look for energy star fridges. In order to prevent further destruction of ozone layer, we must curb the use of ozone depleting substances which release CFCs. Some of the items which contain CFCs are deodorants, aerosol sprays, refrigerators. Yes, we can prevent further depletion of ozone layer by reducing the use of ozone depleting substances. These substances contain CFCs which initiate the process of ozone depletion.
CFC are useful in industry. They are used as coolants.
CFCs (chloro-fluoro-carbons) are harmful to the ozone layer. they used to be used in aerosol sprays and fridges until scientists discovered they were causing holes to form in the ozone layer. they aren't used anymore, but some developing countries are still producing them. ban the use of CFCs worldwide, and you would definitely help stop the destruction of the ozone layer.
Aerosol sprays used to be powered by CFCs (chlorofluorocarbons), which were destroying the ozone layer. Thanks to the Montreal Agreement, the whole world agreed to stop making CFCs and the ozone layer is now slowly recovering. Scientists hope it will be fully restored by around 2050.
There are no CFCs as they where banned because they react with the ozone layer O3 but they where mostly used in Australia which is why there is an opening in the ozone layer.CFCs are released when we use aerosol sprays, refridgerators and air conditioning units.
CFCs were the compressed gas that was used as "spring" to push the can contents out of the container. CFCs have been replaced with HCFCs as a consequence of the Montreal Protocol.
Yes, CFC's are used in sprays. They are used in aerosols too.
Today propane is used.
Chlorofluorocarbons (CFCs) were once used as propellants in aerosol cans, but since the Montreal Protocol was agreed to in 1989, they have been replaced in nearly every country. This is because of the negative effects CFCs have on Earth's ozone layer. Aerosols are now propelled by mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane. Food sprays use nitrous oxide and carbon dioxide.
Liquefied Petroleum Gas (LPG).
chlorofluorocarbons (CFCs)
Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compound in aerosol-spray propellants. Their use has been discontinued under the Montreal Protocol. answer is: FLUOROCARBON..
Ozone layer
The 1987 Montreal Protocol got all countries to agree to phase out chlorofluorocarbons (CFCs) which were then used in aerosol sprays and refrigeration. Chlorine from CFCs destroyed ozone in the ozone layer which led to the weakening of the layer. Now in 2012 scientists believe that ozone seems to be no longer being destroyed, but it will take up to 2060 before the ozone layer has repaired itself.
CFC's have uses in household as well. It is used in deodorant, refrigerators, air conditioners, aerosol sprays etc.
