4 gases produced by human activities?
Carbon dioxideMethaneCFCs (chlorofluorocarbons)HCFCs
What is the cooling element in the refrigerator?
The evaporation coils, where the HCFCs absorb heat and evaporate.
The synthetic lubricant presently used with ternary blends containing HCFCs is?
It's alkyl-benzene.
What are the gases in refrigerators except CFCs?
HCFCs (Hydrochloroflourocarbons) and HFCs (Hydroflourocarbons). HCFCs are not as destructive to the ozone layer as CFCs are, as they are most reactive in the troposphere. Some of the chlorine still reaches the stratosphere, however, which is why HCFCs are being phased out via the Montreal Protocol. HFCs are not destructive to the ozone at all, however some of them are over 1000 times a more potent greenhouse gas than CO2. HFCs, while they may be safe for the ozone, contribute to global warming.
What are HCFCs and what is their effect on the ozone hole and on global warming?
Hydrochlorofluorocarbons (HCFCs or Freon) are the replacement for chlorofluorocarbons (CFCs). The chlorine released from CFCs is very destructive of the ozone layer. HCFCs are less stable than CFCs and much of this gas breaks up before it reaches the lower stratosphere where the ozone layer is. However, some chlorine from HCFCs is still reaching and damaging the ozone layer. Other alternatives, hydrofluorocarbons (HFCs), which have no chlorine have been developed instead. These have no effect on the ozone layer. Unfortunately, one of the replacements, HFC-134a (aka R-134a), for example, used in automobile air conditioning units, is 1430 more powerful as a greenhouse gas than carbon dioxide (CO2).
Is the sale of HCFC banned?
The sale of new or imported HCFCs has been banned in many countries due to their ozone-depleting properties. However, existing supplies can still be used for servicing existing equipment until alternatives are available. Efforts are being made to phase out the use of HCFCs in favor of more environmentally friendly alternatives.
Which refrigerant decomposes at altitudes causing very little chlorine to reach the stratospheric ozone layer- CFCs- HFCs- Ammonia or HCFCs?
CFC's
How are cfcs used in aerosol?
CFCs were the compressed gas that was used as "spring" to push the can contents out of the container. CFCs have been replaced with HCFCs as a consequence of the Montreal Protocol.
Does an air conditioner contain chlorofluorocarbons?
Perhaps yes or perhaps no. Don't mean to be a wise guy, but in the strict sense, chlorofluorocarbon refrigerants have no hydrogen in them. They have only chlorine, fluorine and carbon. These refrigerants have been demostrated to be harmful to the ozone layer, though, and have been banned to a large extent by treaty. Only a few of the "old style" units remain in use. You may or may not have one, and that's why the "yes or no" answer. There used to be lots of chlorofluorocarbon (CFC) refrigerants, but now we have what are called HCFCs to replace them. The HCFCs are a lot less damaging to the ozone layer, and, though they aren't as effective as refrigerants, they are less harmful to the environment. HCFCs are CFCs with a bit of hydrogen in them. We're not splitting hairs here, but it is important to keep our facts straight. Wikipedia has a short blurb on CFCs and HCFCs, and it is tucked inside the post on haloalkanes. No sweat. Just surf on over and read just that section. It's not rocket science. A link is provided.
How pollution related to earth science?
Pollution is when poisionous gases, debris, HCFCs, the Greenhouse effect etc. damage the Earth, which plays a big role in earth sciences.
What is freon recapture?
The Clean Air Act of 1990 requires recapture recycling and safe disposal of chlorofluorocarbons CFCs and hydrochlorofluorocarbons HCFCs used in air conditioners refrigerators and freezers as coolant Under the Act no one may accept an item containing CFCs and HCFCs for recycling or disposal unless the Freon contained within it isproperly removed and the owner, hauler, or appliance company can show proof of proper removal. It is also unlawful for any person to knowingly release or vent CFCs or HCFCs into the air.The EPA requires certification for all technicians removing Freon as of 11 14 1994For more information call the EPA s Stratospheric Protection Hotline at 800 296 1996
Which type of chemicals destroy the ozone that protects people from harmful ultraviolet light?
The chemicals that destroy the ozone are CFCs and HCFCs. They react with ozone to deplete it which protects us from harmful radiations of the sun.
