3 ημέρες πριν · Methane is a hydrocarbon that is a gas at room temperature (20°C). Its molecular formula is CH 4, so it has one carbon atom and four hydrogen atoms per molecule. It is often found as the main part of natural gas. Methane is a greenhouse gas 22 times more effective than carbon dioxide.

Methane is a greenhouse gas with a global warming potential of 22 (meaning that it has 22 times the warming ability of carbon dioxide). Methane results from the decomposition of certain organic matters in the absence of oxygen. It is therefore also classified as a biogas. Principal sources are decomposition of organic wastes
23 Ιαν 2019 · Methane is a simple gas, a single carbon atom with four arms of hydrogen atoms. Its time in the atmosphere is relatively fleeting compared to other greenhouse gases like CO 2 —any given...
