Introduction. Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and aerosols are very important greenhouse gases. CFCs

Another group of greenhouse gases includes the chlorofluorocarbons (CFCs) . CFCs have been responsible for depleting the ozone layer. as they destroy ozone

Unfortunately, these refrigerants have a large impact on our environment. For decades, CFCs have already been known to deplete ozone and are also to blame for global warming. To be able to understand CFCs further, let’s start by learning what it really is. CFC stands for chlorofluorocarbon Definition of chlorofluorocarbon : any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC CFCs are a class of carbon fluorine compounds synthetically made for refrigerant gas. The reason these were chosen was they did very little corrosion inside allowing long device life and were essentially inert and nontoxic to humans.

Chlorofluorocarbon definition is - any of several simple gaseous compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants and in the manufacture of plastic foams, and that are believed to be a major cause of stratospheric ozone depletion —abbreviation CFC. 2021-03-16 · Definition of 'CFC'. CFCs are gases that are used in things such as aerosols and refrigerators and can cause damage to the ozone layer.

Chlorofluorocarbons are more commonly referred to as CFC alternatives.

Manufacturers have used this compound to make cleaning solvents, refrigerants, and aerosol propellants, in some cases, even plastic foams. A few common products include Freon and other refrigerants. CFC - a fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans; "the chlorine in CFCs causes depletion of atmospheric ozone" chlorofluorocarbon HCFC , hydrochlorofluorocarbon - a fluorocarbon that is replacing chlorofluorocarbon as a refrigerant and propellant in aerosol cans; considered to be somewhat less destructive to the atmosphere Chlorofluorocarbons, also known as CFCs, consist of chemical compounds made up of chlorine, fluorine and carbon.
