Final answer:
The GWP of Isobutane (R600a), propane (R-290), and R-441A is much lower compared to synthetic fluorinated gases like HFCs and HCFCs, which have high GWPs due to their long life in the atmosphere and strong greenhouse effect.
Step-by-step explanation:
The global warming potential (GWP) of Isobutane (R600a), propane (R-290), and R-441A are significantly lower compared to several other refrigerants, specifically synthetic fluorinated gases such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs). These synthetic gases have high GWPs, sometimes in the thousands, due to their long atmospheric lifetimes and their strong ability to absorb and scatter energy, which contributes to the greenhouse effect. For example, HFC-134a and HCFC-141b are two such gases with high GWPs. The goal in finding alternatives with lower GWPs, like R600a and R-290, is to reduce the potential impact on global warming from refrigerant emissions.
