chlorofluorocarbons
organic compounds that contain carbon, chlorine, and fluorine atoms. CFCs are highly effective refrigerants that were developed in response to the pressing need to eliminate toxic and flammable substances, such as sulfur dioxide and ammonia, in refrigeration units and air conditioners. The most common commercial CFCs, marketed under the trade name Freon, are trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12). Commercial CFCs are nonflammable, noncorrosive, nontoxic, and odorless, and their vapor pressures and heats of vaporization made them very suitable for refrigeration applications. They were also widely used as aerosol propellants, cleansing agents for electrical and electronic components, and foaming agents in shipping-plastics manufacturing.

It's CFC(Chlorofluorocarbons) gas.The invention of chlorofluorocarbons (CFCs) in the late 1920s and early 1930s stemmed from the call for safer alternatives to the sulphur dioxide and ammonia refrigerants used at the time. Chlorofluorocarbons were chosen for their safety and for their advantageous chemical properties. These compounds are low in toxicity, nonflammable, noncorrosive, and nonreactive with other chemical species, and have desirable thermal-conductivity and boiling-point characteristics. These features led to increased demand as more applications arose for CFC use.

Air conditioners and refrigirators release CFC's (Chlorofluoro carbons)which are the main cause of depletion of ozone.

Chloroflorocarbons, or CFC's for short. They are not used these days as less harmful substitutes have been found. The problem is with older models that have reached the end of their useful lives.

warmth flow for planets, is composed of on the transmission of sunshine. warm air would not vent from a planet with an ecosystem, or it could have no ecosystem. The temperature of an emitting floor (like Earth's floor) acts like a "black physique emitter", and on the temperatures of Earth's floor, the characteristic emission is infrared. Earth is on worry-unfastened warmer than our Moon, because of the fact our ecosystem shall we seen easy in quite, yet would not enable infrared easy out quite. that's referred to as the greenhouse result. Greenhouse gases grant this greenhouse result, and in our ecosystem, those gases are broadly speaking: - water vapor - carbon dioxide (CO2) - methane - ozone (vulnerable, yet nevertheless a participant) ... all have been shown to have greater suitable by utilising one hundred% to 4 hundred% because of the fact the early 1700s. apart from ozone. will improve interior the quantities of those greenhouse gases, ability seen easy can nevertheless get in, even though it quite is much greater stable for them to get out.

cloro fluro carbon (cfc)
it react with ozone o3 and releases gas.. becoz of this reaction.. !! there is depletion in ozone..
moreover the this gas is produced not only by fridge but also perfumes wat we r using..!!
many solutions to avoid this cfc production being carried on.. but still to eradicate it the people shud come fwd and stop using these perfumes and other products with produces cfc..

It is a chemical named R12 more commonly known as freon, but it is not used as much today as in the past. CFC's is a broad category of chemicals which freon is grouped with.

It is called CFC or Chloro Fluro Carbon..
It also causes Acid Rain... and Many Ecological imbalances...

as they produce CFC that is chloroflorocarbon it leads to ozone depletion.
