Web28 de jun. de 2024 · But the methane starts to break down and leave the atmosphere relatively quickly. As more time goes by, and as more of that original ton of methane disappears, the steady warming effect of the CO 2 slowly closes the gap. Over 20 years, the methane would trap about 80 times as much heat as the CO 2.

The heat of combustion of ethanol, ΔHc° (C2H6O, l) = 2*393.51 + 6*142.915 + (-277.6) = 1366.91 kJ/mol. This can be converted to kJ per mass units: The molweight of ethanol is (2*12.01 + 6*1.01 + 1*16.00) = 46.08 g/mol fm kurzus jelentése
