This is a big issue now a day as scientists discovers new global warming threat as melting permafrost releases millions of tons of a gas 20 times more damaging than carbon dioxide. Underground stores of methane are important because scientists believe their sudden release has in the past been responsible for rapid increases in global temperatures, dramatic changes to the climate, and even the mass extinction of species.

Gas of Pluto?

Pluto's thin atmosphere mainly consists of nitrogen, with minor amounts of methane and carbon monoxide. It is not considered a gas giant like Jupiter or Saturn due to its small size and low gravity, which prevents it from holding onto thick layers of gas.


What is the Threshold limit value for methane gas?

The Threshold Limit Value (TLV) for methane gas is set at 1000 parts per million (ppm) as a time-weighted average for an 8-hour workday. Concentrations above this limit may pose health risks to individuals exposed to methane gas.


How long does it take methane to form?

Methane can form relatively quickly in natural environments through the decomposition of organic matter by bacteria in oxygen-deprived conditions, a process known as methanogenesis. The exact time it takes for methane to form can vary depending on factors such as temperature, pressure, and the availability of suitable substrates for methanogenic bacteria. In some cases, methane can be produced in as little as a few days to weeks under favorable conditions.


Why does a bomber not drop its bomb vertically above the target?

Dropping the bomb at an angle allows the aircraft to safely release the bomb from a distance, reducing the risk of being hit by enemy defenses. Additionally, releasing the bomb at an angle helps to achieve better accuracy by taking into account factors like wind speed and trajectory.


What is methane gas and how is it used?

Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane, and the principal component of natural gas. Methane's bond angles are 109.5 degrees. Burning methane in the presence of oxygen produces carbon dioxide and water. The relative abundance of methane makes it an attractive fuel. However, because it is a gas at normal temperature and pressure, methane is difficult to transport from its source. In its natural gas form, it is generally transported in bulk by pipeline or LNG carriers; few countries transport it by truck.Methane was discovered and isolated by Alessandro Volta between 1776 and 1778 when studying marsh gas from Lake Maggiore.Methane is a relatively potent greenhouse gas. Compared with carbon dioxide, it has a high global warming potential of 72 (calculated over a period of 20 years) or 25 (for a time period of 100 years).[2] Methane in the atmosphere is eventually oxidized, producing carbon dioxide and water. As a result, methane in the atmosphere has a half life of seven years[citation needed].The abundance of methane in the Earth's atmosphere in 1998 was 1745 parts per billion (ppb), up from 700 ppb in 1750. By 2008, however, global methane levels, which had stayed mostly flat since 1998, had risen to 1,800 ppb[3]. By 2010, methane levels, at least in the arctic, were measured at 1850 ppb, a level scientists described as being higher than at any time in the previous 400,000 years.[4] (Historically, methane concentrations in the world's atmosphere have ranged between 300 and 400 ppb during glacial periods commonly known as ice ages, and between 600 to 700 ppb during the warm interglacial periods).In addition, there is a large, but unknown, amount of methane in methane clathrates in the ocean floors. The Earth's crust contains huge amounts of methane. Large amounts of methane are produced anaerobically by methanogenesis. Other sources include mud volcanoes, which are connected with deep geological faults, landfill and livestock (primarily ruminants) from enteric fermentation
