  2. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.

    IUPAC chemical name; molecular formula; CAS registry number / blend name; Atmospheric lifetime in years; Semi-empirical ozone depletion potential, ODP (normalized to be 1 for R-11) Net global warming potential, GWP, over a 100-year time horizon (normalized to be 1 for R-744, carbon dioxide)

  4. Liquid carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Liquid_carbon_dioxide

    Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]

  5. List of gases - Wikipedia

    en.wikipedia.org/wiki/List_of_gases

    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.

  6. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    Subliming dry ice pellet, with white frost on the surface. Dry ice means the solid form of carbon dioxide.It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure and sublimes directly from the solid state to the gas state.

  7. Carbon dioxide in Earth's atmosphere - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's...

    Carbon dioxide is often mentioned in the context of its increased influence as a greenhouse gas since the pre-industrial (1750) era. In 2013, the increase in CO 2 was estimated to be responsible for 1.82 W m −2 of the 2.63 W m −2 change in radiative forcing on Earth (about 70%). [48]

  8. Glossary of chemical formulae - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemical_formulae

    This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. ... carbon dioxide: 124-38-9 CO 3: carbon trioxide: 12144-05-7

  9. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    Carbon dioxide is written CO 2; sulfur tetrafluoride is written SF 4. A few compounds, however, have common names that prevail. H 2 O, for example, is usually termed water rather than dihydrogen monoxide, and NH 3 is preferentially termed ammonia rather than nitrogen trihydride.
