About: Liquid carbon dioxide

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Liquid carbon dioxide is the liquid state of carbon dioxide (CO2), 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). Low-temperature carbon dioxide is commercially used in its solid form, commonly known as "dry ice". Solid CO2 sublimes at 194.65 K (−78.5 °C; −109.3 °F) at Earth atmospheric pressure — that is, it transitions directly from solid to gas without an intermediate liquid stage. The uses and applications of liquid carbon dioxide include decaffeinating coffee, extracting virgin olive oil from olive paste, in fire extinguishers, and as a coolant.
