Metan gas
Uranus' atmosphere is made up of hydrogen, helium, and methane.
The simplest aliphatic hydrocarbon, CH4, being a constituent of natural gas
Cattle emit a large amount of methane.
Any of very many derivatives of methane
The principal constituent of natural gas
a greenhouse gas whose importance has increased significantly in greenhouse warming scenarios as concentrations continue to rise Methane is about 20 times more effective as a greenhouse gas than carbon dioxide, making it an important species in the global warming estimates It is currently increasing at a rate of ~1% per year with concentrations of approximately 1 75 ppb Major natural methane sources are known to include fermentation in ruminant animals, anaerobic decay of organic material in rice paddies, natural wetlands Significant anthropogenic sources include landfills; inadvertent release of trapped and adsorbed gas during coal mining, natural gas production and distribution, and oil exploration; incomplete combustion during biomass burning Due to its relatively long chemical lifetime, methane can also be transported into the stratosphere where it can contribute to ozone loss
Methane is a colourless gas that has no smell. Natural gas consists mostly of methane. a gas that you cannot see or smell, which can be burned to give heat (methyl). or marsh gas Organic compound, chemical formula CH4, colourless, odourless gas that occurs in natural gas (called firedamp in coal mines) and from bacterial decomposition of vegetation in the absence of oxygen (including in the rumens of cattle and other ruminants and in the gut of termites). The simplest member of the paraffin hydrocarbons, methane burns readily, forming carbon dioxide and water if supplied with enough oxygen for complete combustion or carbon monoxide if the oxygen is insufficient. Mixtures of 5-14% methane in air are explosive and have caused many mine disasters. The chief source of methane is natural gas, but it can also be produced from coal. Abundant, cheap, and clean, methane is used widely as a fuel in homes, commercial establishments, and factories; as a safety measure, it is mixed with trace amounts of an odorant to allow its detection. It is also a raw material for many industrial materials, including fertilizers, explosives, chloroform, carbon tetrachloride, and carbon black, and is the principal source of methanol
A gas created by anaerobic decomposition of organic compounds Natural gas is composed mostly of methane Methane is a so-called greenhouse gas (see greenhouse effect) Agricultural wastes, specially animal wastes, are a major source of methane releases to the atmosphere
A hydrocarbon compounds that is the major component of natural gas; the most common gas formed in coalmines
Methane is an odorless gas produced by the decomposition of organic matter
Colourless, odourless gas (CH4) The simplest hydrocarbon and the main constituent of natural gas Produced during the process of breakdown of organic matter Can be converted to methanol by catalytic oxidation
A light, colorless, gaseous, inflammable hydrocarbon, CH4; marsh gas
– A hydrocarbon (CH4), which is colorless, odorless and lighter than air; the major component of natural gas
A flammable hydrocarbon gas that results from the decay of organic material as in marshes and coal mines, and is the main constituent of natural gas
(CH4) (biocon) (chem) An odorless, colorless gas, nearly insoluble in water, which burns with a pale, faintly luminous flame to produce water and carbon dioxide (or carbon monoxide if oxygen is deficient) F - methane S - metano
A hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 24 5 Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and oil, coal production , and incomplete fossil fuel combustion The atmospheric concentration of methane has been shown to be increasing at a rate of about 0 6% per year and the concentration of about 1 7 parts per million by volume (ppmv) is more than twice its preindustrial value However, the rate of increase of methane in the atmosphere may be stabilizing
- A hydrocarbon compound that is the primary component of natural gas It is a greenhouse gas and is reported separately from the category of gases called volatile organic compounds (VOCs)
