Question

core - question # 17
how do the global warming potentials of isobutane (r - 600a), propane (r - 290), and r - 441a compare to the gwps of hfc - 134a, r - 404a, and r - 410a?
a they are significantly higher.
b they are significantly lower.
c they are approximately equal.
d they are just slightly higher.

Explanation:

Isobutane (R - 600a), propane (R - 290), and R - 441A are hydrocarbons or blends with relatively low global - warming potentials compared to hydrofluorocarbons (HFCs) like HFC - 134a, R - 404A, and R - 410A which have high GWP values.

Answer:

B. They are significantly lower.
