  2. Marsh gas - Wikipedia

    en.wikipedia.org/wiki/Marsh_gas

    Bubbles of methane, created by methanogens, that are present in the marsh, more commonly known as marsh gas. Marsh gas, also known as swamp gas or bog gas, is a mixture primarily of methane and smaller amounts of hydrogen sulfide, carbon dioxide, and trace phosphine that is produced naturally within some geographical marshes, swamps, and bogs.

  3. List of gases - Wikipedia

    This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...

    en.wikipedia.org/wiki/Methane

    Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.

  6. List of highly toxic gases - Wikipedia

    en.wikipedia.org/wiki/List_of_highly_toxic_gases

    Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.

    As distributed, contains an extremely high proportion of simple hydrocarbon "illuminants", including oliefant gas (ethylene, C 2 H 4) and acetylene gas (C 2 H 2), as well as propane gas (C 3 H 8), marsh gas (methane, CH 4), hydrogen (H 2), and a small amount of carbonic oxide (carbon monoxide, CO). 1000–1500: 40–60

  8. Will-o'-the-wisp - Wikipedia

    en.wikipedia.org/wiki/Will-o'-the-wisp

    The idea of the will-o'-the-wisp phenomena being caused by natural gases can be found as early as 1596, as mentioned in the works of Ludwig Lavater. [b] [53] In 1776 Alessandro Volta first proposed that natural electrical phenomena (like lightning) interacting with methane marsh gas may be the cause of ignis fatuus. [54]

  9. Marsh - Wikipedia

    en.wikipedia.org/wiki/Marsh

    A marsh in Jyväskylä, Finland. Marshes differ depending mainly on their location and salinity. These factors greatly influence the range and scope of animal and plant life that can survive and reproduce in these environments. The three main types of marsh are salt marshes, freshwater tidal marshes, and freshwater marshes. [3]
