Question

According to the EPA, of the refrigerants listed below, which types of refrigerants will not contribute to global warming?

1) CFCs
2) HCFCs
3) HFCs
4) None of the above

Answer 1

CFCs, HCFCs, and HFCs are the listed refrigerants that will all contribute to global warming.

Step-by-step explanation:

According to the EPA, of the refrigerants listed below, which types of refrigerants will not contribute to global warming?

1. CFCs: Chlorofluorocarbons (CFCs) are synthetic chemicals that were widely used as refrigerants, propellants, and solvents. However, CFCs contribute to ozone depletion and global warming, so they are no longer used.
2. HCFCs: Hydrochlorofluorocarbons (HCFCs), such as HCFC-22 and HCFC-123, are also synthetic chemicals that have been used as refrigerants. While they have less impact on the ozone layer compared to CFCs, they are still greenhouse gases that contribute to global warming.
3. HFCs: Hydrofluorocarbons (HFCs) are synthetic chemicals that have been developed as replacements for CFCs and HCFCs. While they do not contribute to ozone depletion, they are powerful greenhouse gases that contribute to global warming. Therefore, none of the refrigerants listed (CFCs, HCFCs, and HFCs) will not contribute to global warming.

In summary, all the refrigerants listed (CFCs, HCFCs, and HFCs) contribute to global warming.
