What class of molecules has CFCs replace?
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.
Why is an HCFC refrigerant considered less harmfull to the ozone than a CFC refrigerant?
HCFC refrigerants contain hydrogen, which makes them less harmful to the ozone layer compared to CFC refrigerants that contain chlorine. When CFCs break down in the atmosphere, they release chlorine atoms that can destroy ozone molecules. In contrast, HCFCs break down more quickly and release fewer chlorine atoms, reducing their ozone-depleting potential.
What is an example of CFC refrigerant?
The example of CFC is R-12. It is being used as a refrigerant.
Which gas is used instead of CFC in Refrigerators now-a-days?
LPG - Liquid propane gas or other Hydrocarbon derivatives... Soft CFC's, they added hydrogen to the CFC's previously used that were called hard CFC's. By doing this it won't allow the CFC's to travel up to the stratosphere, where it breaks down the ozone. With the added hydrogen will stop it in the troposphere and combine to form compounds such as CO2 + HCl (or HF), therefore not harmful to the ozone. Examples CH2Cl (HCFC-22) or CHCl2-CF2 (HCFC-123)
Appliances containing cfc refrigerant can be evacuated to atmopheric pressures when?
Small appliances containing HCFC refrigerants can be evacuated to atmospheric pressure when leaks make evacuation to the prescribed level unreachable. HCFC stands for hydrochlorofluorocarbons.
How does hcfc destroy ozone layer?
HCFC do not destroy ozone. They are an alternative to CFC's.
What substance depletes ozone in the stratosphere?
CFC's and HCFC's
What class of molecules has CFCs replace?
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.
IS R-134a an HCFC refrigerant?
It's a CFC refrigerant.
How do CFC's substitues prevent the destruction of the stratospheric ozone?
CFC's have new substitutes in market. They are called as HCFC's.
Which element help protect the ozone layers?
HCFC protect the ozone. They are an alternative to CFC's.
Ozone freindly chemicals used by cfcs?
Nowadays we have alternatives for CFC's. These are called HCFC's.
What is the alternative solution for destroying ozone molecules by using AC?
There is an alternate solution for CFC's. These are HCFC's.
What are the substitute for chlorofloro carbon which is responsible for ozone depletion?
There is a substitute for CFC's in market. It is called HCFC's.
What can you do to prevent the ozone from disappearing?
In order to prevent depletion, ban the use of CFC's. You can use HCFC's.
What are two ways to stop the Ozone eaters?
Ozone eaters are CFC's. They should be stopped and HCFC's be used.
Why is an HCFC refrigerant considered less harmfull to the ozone than a CFC refrigerant?
