Which refrigerants contain the most chlorine?
Refrigerants that contain chlorine are known as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Among these, CFC-11 (trichlorofluoromethane) and CFC-12 (dichlorodifluoromethane) are two of the refrigerants that contain the most chlorine.
What refrigerant contains a CFC R-500 R-22 R-134a or r-123?
R-22 is the refrigerant that contains CFC (chlorofluorocarbon). R-134a does not contain CFCs but is considered an HFC (hydrofluorocarbon) refrigerant. R-500 contains a mixture of CFC-12 and CFC-22. R-123 is a halocarbon refrigerant but does not contain CFCs specifically.
What happens to the CFC molecule in the lower atmosphere?
In the lower atmosphere, CFC molecules undergo photolysis when they are exposed to ultraviolet radiation from the sun. This process breaks down the CFC molecule into chlorine atoms, which can then catalyze the destruction of ozone molecules. This contributes to the depletion of the ozone layer.
Why are the effects of the CFC gases ban taking so long to work?
CFC gases have a long atmospheric lifetime, meaning they can persist for many years after being emitted. It takes time for them to break down and be removed from the atmosphere. Additionally, some older equipment and products containing CFCs may still be in use, delaying the full impact of the ban.
What green house gases do not occur in nature?
Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride are examples of greenhouse gases that do not occur naturally in the atmosphere but are produced through human activities, such as industrial processes and the use of certain products.
Is cfc manmade?
Yes, it is. CFC's are coolants created by man.
When was The CfC-Stanbic Bank Magnate created?
The CfC-Stanbic Bank Magnate was created on 2011-10-27.
When was Pierre Desgraupes born?
Pierre Desgraupes was born on December 18, 1918, in Angoulme, Charente, France.
When was Pierre Cheminat born?
Pierre Cheminat was born on June 14, 1972, in Angoulme, Charente, France.
How was the ozone created and destoryed?
Ozone was created by UV rays. It is destroyed by CFC's.
Why is the ozone layer breaking?
The ozone layer is breaking due to CFC's. They are man created ODS.
What ıs ozone hole?
The absence of ozone molecules is termed as ozone hole. It is created by CFC's.
When and by whom were the cfc created?
Chloroflourocarbons were first created in 1928 as non-toxic, non-flamable refrigerants, and were first produced commercially in the 1930's by DuPont. The first Chlorofluorocarbon was CFC-12, a single carbon with two chlorines and two Fluorines attached to it.
What is the interaction of CFC and stratospheric ozone?
CFC and ozone interact often. Here CFC's deplete ozone.
What is most dagerous for atmosphare cfc or so2?
cfc
Is ozone promoted by CFC's?
No, its not. ozone is destroyed by CFC's.
Which gas has highest ozone deplition?
CFC gases depletes the ozone. Ozone holes have been created because of it.
