What are CFCs answer?
Answer. 62.4k+ views. 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 are CFCs and give examples?
Chlorofluorocarbons or CFCs They are man-made gas. It contains carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane. Commonly known by the name freon, the manufacture of CFCs. CFC is also one of those gases involved in the greenhouse effect.
What are CFCs and why are they damaging?
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 are CFCs class 10th?
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 is CFCs full form?
CFCs are gases that were widely used in the past in things such as aerosols and refrigerators and can cause damage to the ozone layer. CFC is an abbreviation for ‘chlorofluorocarbon’.
What are CFCs Class 5?
Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are fully or partly halogenated paraffin hydrocarbons that contain only carbon (C), hydrogen (H), chlorine (Cl), and fluorine (F), produced as volatile derivatives of methane, ethane, and propane.
What are CFCs for Class 8?
Chlorofluorocarbons (CFCs) are pollutants which areused in refrigerators and air conditioners. They damage the ozone layer of the atmosphere. When air is contaminatedby unwanted substances which havea harmful effect on both the living andthe non-living, we call it airpollution.
Where do CFCs come from?
Answer and Explanation: CFCs come from a variety of appliances where they are used as coolants. Freon is one example of a CFC. Though it is not used in new appliances, freon was the main coolant used in refrigerators and air conditioners for a number of years.
What do CFCs do to our atmosphere?
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 products are CFC’s found in?
Refrigerators and Air Conditioners. The most common emitter of CFCs are refrigerants,particularly those used after the 1930s.
How do CFCs affect the environment?
Inhalation of CFCs affects the central nervous system, according to the New Hampshire Department of Environmental Sciences. The result is intoxication similar to that produced by alcohol, including lightheadedness, headaches, tremors and convulsions. Inhalation of CFCs can also disturb the heart rhythm, which can lead to death.
