WebCFCs atmospheric effects are not limited to the ozone layer depletion only as the infrared absorption band present in the atmosphere prevents heat from escaping from the earth’s atmosphere. CFCs have their strongest absorption bands from C-F and C-CI bonds in the spectral region of 7.8-15.3 m, referred to as the Atmospheric Window. WebCFC stands for chlorofloro carbon. The ozone layer is getting depleted by the action of chlorofluorocarbons (CFCs) used as coolant in refrigerators and perfumes. The CFCs are acted upon by UV rays in the stratosphere, liberating the Cl atoms, which act as catalysts to degrade ozone into molecular oxygen.
WebChlorofluorocarbons (CFCs) are artificially made chemical compounds used as refrigerants, cleaning solvents, aerosol propellants, and blowing agents for foam packaging in many commercial applications. They typically consist of chlorine, fluorine, carbon, and hydrogen. Freon ®, a trade name, is often used to refer to them. WebMost common CFCS abbreviation full forms updated in March 2024. Suggest.
