What is long form of CFC?

What is long form of CFC?

Chlorofluorocarbon(CFC) is any of various halocarbon compounds consisting of carbon, hydrogen, chlorine, and fluorine. CFC were once used widely as aerosol propellants and refrigerants. Chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer.

What CFC meaning?

: 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.

What are CFC Class 9?

Chlorofluorocarbons (CFC) are gases used for various purposes including solvents, refrigerants and aerosol sprays. They are organic chemicals and contain carbon, (sometimes hydrogen,) chlorine, and fluorine.

What are examples of CFC?

An example of a refrigerant CFC is dichlorodifluoromethane, CF2Cl2 (also known as CFC-12), which boils at -30°C. Another once-common CFC is trichlorofluoromethane, CFCl3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world.

What is the full form of HFC?

hydrofluorocarbon (HFC), any of several organic compounds composed of hydrogen, fluorine, and carbon. HFCs are produced synthetically and are used primarily as refrigerants.

Is CFC a greenhouse gas?

The compounds that only contain carbon, chlorine, and fluorine are called chlorofluorocarbons (CFCs). Chlorofluorocarbons are exceptionally strong greenhouse gases and are also responsible for the destruction of stratospheric ozone.

What is CFC in global warming?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

What is CFC in social science?

CFC refers to Chloro Fluoro Carbon. Any of a class of compounds of carbon,hydrogen,chlorine and fluorine,typically gases used in refrigerants and aerosol propellants. they are harmful to the ozone layer in the earth’s atmosphere owing to release the chlorine atoms on exposure to ultraviolet radiation.

What is the full form of CFC and UNEP?

Answer: CFC :- chlorofluorocarbons. UNEP :- the United nations environment programme.

How long do CFCs stay in atmosphere?

The environmental concern for CFCs follows from their long atmospheric lifetime (55 years for CFC-11 and 140 years for CFC-12, CCl2F2)9 which limits our ability to reduce their abundance in the atmosphere and associated future ozone loss.

Are CFCs inert?

At the time, CFCs were in wide use in refrigeration, air conditioning and aerosol spray cans. The compounds are inert and essentially nontoxic, characteristics that made them well-suited for these applications.

What is HFC used for?

Hydrofluorocarbons (HFCs) are greenhouse gases (GHGs) commonly used by federal agencies in a wide variety of applications, including refrigeration, air-conditioning (AC), building insulation, fire extinguishing systems, and aerosols.
