Natural gas is mostly made up of methane, a nasty greenhouse gas that contributes to climate change and global warming. As it is released, that methane flows up into the atmosphere, raisingglobal temperaturesto dangerous levels. According toInsideClimate News, scientists predict that we have until...
Natural gas is a fossil fuel that was created from decaying organic matter deep underneath the Earth’s surface millions of years ago. It’s found in underground deposits called “reservoirs” and is mostly made up of methane. Over the past couple of decades, new drilling methods like hydrauli...
nat·u·ral gas (năch′ər-əl) A mixture of hydrocarbon gases that occurs naturally beneath the Earth's surface, often with or near petroleum deposits. Natural gas contains mostly methane, but also has varying amounts of ethane, propane, butane, and nitrogen. It is used as a fuel...
Natural gas consists mostly of methane and can be found in large reserves across the world. Due to its low volumetric energy density, natural gas is commonly stored in a compressed state in high-pressure storage vessels as CNG, with internal pressures of 20 MPa or more [1]. H2 is another...
Natural gas is often found dissolved in oil at the high pressures existing in a reservoir, and it can be present as a gas cap above the oil. In many instances it is the pressure of natural gas exerted upon the subterranean oil reservoir that provides the drive to force oil up to the ...
2.2 Natural gas Natural gas is a gaseous hydrocarbon-based fossil fuel which consists primarily of methane but contains significant quantities of ethane, propane, butane and other hydrocarbons up to octane as well as carbon dioxide, nitrogen, helium, and hydrogen sulfide (Table 2.5). Natural gas ...
Reading: Natural Gas Natural gasis a fossil fuel formed when layers of buried plants, gases, and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in natural gas. ...
题干中的natural gas“天然气”和wind“风”是两种能源,故可推知后半句是other forms of energy“其他形式的能源”。题意是“很多国家正在提高对天然气,风或其他形式的能源的利用。”故答案为A。 练习册系列答案 赢在起跑线快乐寒假河北少年儿童出版社系列答案 春雨教育考必胜中考试卷精选系列答案 天利38套解锁...
