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 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
An odorless, colorless, flammable gas with the formula CH4 that is the primary constituent of natural gas
A colorless, odorless gas composed of carbon and hydrogen Methane occurs naturally in marshes, rice paddies, oil wells, and volcanoes Methane is also formed in the digestive track of cattle and termites Methane is a greenhouse gas in the atmosphere because it absorbs long-wavelength radiation from the Earth's surface
The most simple of the hydrocarbons formed naturally from the decay of vegetative matter, similar to that which formed coal It is the principal component of natural gas and is a radiative gas
- A gaseous carbon compound produced primarily by decomposition of organic compounds under anaerobic (no oxygen) conditions It is an important greenhouse gas, with a global warming potential roughly 21 times that of carbon dioxide It is produced primarily in the gut of ruminant animals and in the anaerobic conditions created by saturated soils (wetlands), sealed landfills, or covered manure lagoons Healthy forests, in the absence of supplemental fertilization, have been shown to be an important methane sink, removing methane from the air through the action of soil organisms The scientific basis for quantifying these methane effects is poorly known at this time, however, and NCOC forestry projects will not, at this time, consider forest effects on methane sources and sinks in project accounting
See Marsh gas, under Gas
A highly flammable gas that is the main constituent of "natural gas" Methane is used as a fuel and in manufacturing chemicals
also called marsh gas, is composed of one carbon molecule and four hydrogen molecules (CH4) It is lighter than air, colourless, odourless and flammable Methane is produced wherever once-living materials decay It is released from swamps, rice paddies, garbage in landfills, and burning forests It is also produced by animals like cows during the digestive process Since methane has 25 times the heat trapping capability of carbon dioxide, and since methane production is directly related to population growth, methane is a serious contributor to the greenhouse effect [Jenson] However, it helps other chemicals to be released from coal mining, the production of petroleum products, and the use of natural gas
a colorless odorless gas used as a fuel
hydrocarbon gas composed of carbon and hydrogen with a formula of CH4 It is lighter than air, colorless, odorless and flammable It occurs in natural gas and as firedamp in coal mines With the correct amount of oxygen present, methane ignites at 595°C (1103°F)
- the main component of natural gas It also occurs in coal beds and is produced by animals and by the decay of vegetable matter This is the smallest hydrocarbon molecule, with only one carbon atom and four hydrogen atoms
A colorless, nonpoisonous, flammable gas created by anaerobic decomposition of organic compounds A major component of natural gas used in the home
A hydrocarbon with four Hydrogen atoms attached to each Carbon atom (CH4) Methane is called "swamp gas" because it is produced by bacteria when organic matter decomposes under anoxic (oxygen-free) conditions, as in swampy land Methane-producing bacteria are sensitive to oxygen, but they exist in habits such as animal digestive tracts, sanitary landfills, swamps, sludge, and other decaying organic matter, where the oxygen has already been removed by other bacteria Methane can be used as a fuel, and as a gas is significant as a contributor to the greenhouse effect _ the only major greenhouse gas produced in greater amounts by developing countries than industrialized countries (Source: Mintzer, 1992)
– A potentially explosive gas formed naturally from the decay of vegetative matter, similar to that which formed coal Methane, which is the principal component of natural gas, is frequently encountered in underground coal mining operations and is kept within safe limits through the use of extensive mine ventilation systems
(CH4) - the smallest hydrocarbon molecule with one carbon atom and four hydrogen atoms It is the chief constituent of natural gas, but also occurs in coal beds, and is produced by animals and the decay of vegetable material It is a light colourless, odourless flammable gas under normal conditions Methane is the first member in the alkane (paraffin) series At atmospheric pressure, it liquefies at -162°C
The simplest aliphatic hydrocarbon, CH{4}, being a 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
{i} swamp gas; gas obtained from the natural decomposition of organic matter (Chemistry)
- 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)
one of the three major greenhouse gases responsible for climate change (see greenhouse gases) Although there is less methane than carbon dioxide in the atmosphere, methane is a more effective heat-trapping greenhouse gas The IPCC estimates that the global warming potential of methane is 21 times that of carbon dioxide Methane comes from the decay of matter without the presence of oxygen Human activities such as rice cultivation, the rearing of some farm animals (see ruminants), biomass burning, coal mining and natural gas venting are increasing the input of methane into the atmosphere
(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 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
– A hydrocarbon (CH4), which is colorless, odorless and lighter than air; the major component of natural gas
A light, colorless, gaseous, inflammable hydrocarbon, CH4; marsh gas
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
Methane is an odorless gas produced by the decomposition of organic matter
A hydrocarbon compounds that is the major component of natural gas; the most common gas formed in coalmines
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
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
