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 ]
One family of carbon oxides has the general formula C n O 2, or O=(C=) n O — namely, a linear chain of carbon atoms, capped by oxygen atoms at both ends. The first members are CO 2 or O=C=O, the well-known carbon dioxide. C 2 O 2 or O=C=C=O, the unknown and extremely unstable ethylene dione. [17]
Supercritical carbon dioxide (s CO 2 ) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure . Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when cooled and/or pressurised sufficiently.
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
Carbon dioxide hydrate or carbon dioxide clathrate is a snow-like crystalline substance composed of water ice and carbon dioxide. [1] It normally is a Type I gas clathrate . [ 2 ] There has also been some experimental evidence for the development of a metastable Type II phase at a temperature near the ice melting point.
