Abbreviation: CFC. Collins English Dictionary. Copyright © HarperCollins Publishers. We obtain mixing ratios for six gases (CFC-11, CFC-12, HCFC-22, H-1211, H-1301, and SF 6), all of which are important for understanding stratospheric ozone depletion and circulation. After demonstrating the quality of the data through comparisons with ground-based records and aircraft-based observations, we combine them with the latter to demonstrate its potential. CFC gases were originally banned in 2000 after being linked to ozone damage; For example, the CFC number of 11 indicates the number of atoms of carbon, hydrogen, fluorine, 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. What applies to CFC-11 also applies to other synthetic gases, as demonstrated by another recent Empa study, published in the journal PNAS. These findings emphasize the need to be on the lookout before new environmental threats develop on a large scale (see box).

Another once-common CFC is trichlorofluoromethane, CFCl 3 (CFC-11), which boils at 24°C and was once the propellant in around half of all the aerosol cans used in the world. These and other CFCs, and the chemically similar chlorocarbons (such as methylene chloride, CH 2 Cl 2 Examples of chlorofluorocarbon chlorofluorocarbon Similarly, attention to the health and other consequences of an expanding ozone hole led to restrictions upon the release of chlorofluorocarbons … 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. 2008-6-20 · In 1987 an international treaty, the Montreal Protocol, called for reducing CFC use by 50% by 2000. A 1992 amendment to the treaty called for the end of CFC production in industrial countries by 1996, and by 1993 CFC emissions had dropped dramatically.

A relative measure of the warming effect that the emission of a gas might have on the surface troposphere. It is measured as a factor relative to CO 2. CFC definition: CFCs are gases that were widely used in the past in things such as aerosols and | Meaning, pronunciation, translations and examples 2021-04-24 · These gases contribute to atmospheric warming when they absorb infrared radiation emitted by the solar-warmed Earth and transfer their extra energy to the surrounding atmospheric gases. The figure shows that the temperature at the surface of the Earth has increased by about 0.9 °C during the past Many translated example sentences containing "cfc gases" – English-Spanish dictionary and search engine for English translations. 2012-09-26 · For example, HCFC-142b identifies the isomer in which all three hydrogen atoms are attached to the same carbon atom, and the structural formula is written as CH 3 CF 2 Cl. By contrast, HCFC-142 (without the b) refers to an arrangement in which one carbon atom is attached to two hydrogen atoms and one chlorine atom, while the other carbon atom is attached to the third hydrogen atom and two Contextual translation of "cfc gas" into English. Human translations with examples: ga, abx, gas, freon, gases, sludgy, gaseous, fuel gas, cfc rules, concerning gas.

Chlorofluorocarbons (CFCs) were invented. Refrigerants for refrigerators, automobiles and 21 Oct 1999 A common example of deposition is 'rain out': compounds that are soluble in water can be removed from the atmosphere by precipitation. This Although HCFCs are much less damaging to the ozone than CFCs, they are still powerful greenhouse gases (though not as bad as CFCs). For example, R22 Chlorofluorocarbons (CFCs) are an important example of a chlorine-containing source gas.

Before Thomas Midgley Jr. and his associates invented Freon in 1928, the most common refrigerants were dangerous chemicals such as sulfur dioxide, methyl chloride and ammonia. Freon is a combination of several chlorofluorocarbons, or CFCs, which are so chemically inert that engineers believed they had found a miracle Model RI-2002PA is designed to identify vapor gas samples taken directly from CFC refrigerant storage cylinders.
