Methane (US: / ˈmɛθeɪn / METH-ayn, UK: / ˈmiːθeɪn / MEE-thayn) is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
4 paź 2024 · methane, colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Its chemical formula is CH 4.
23 sty 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...
25 wrz 2020 · Methane is a colorless, odorless, and highly flammable gas, and the main component in natural gas, which is used to generate electricity and heat homes around the world. Methane...
Methane is a powerful and short-lived greenhouse gas, with a lifetime of about a decade and Global Warming Potential about 80 times greater than that of carbon dioxide (CO2) during the 20 years after it is released into the atmosphere. (IPCC)
24 paź 2024 · Greenhouse gas - Methane, Climate Change, Emissions: Methane (CH4) is the second most important greenhouse gas. CH4 is more potent than CO2 because the radiative forcing produced per molecule is greater.
Methane Basics. Methane (CH 4) is a powerful greenhouse gas, and is the second-largest contributor to climate warming after carbon dioxide (CO 2). A molecule of methane traps more heat than a molecule of CO 2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO 2 can persist for hundreds of years or more.
