    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is a food additive used as a propellant and acidity regulator in the food industry. It is approved for usage in the EU [121] (listed as E number E290), US, [122] Australia and New Zealand [123] (listed by its INS number 290). A candy called Pop Rocks is pressurized with carbon dioxide gas [124] at about 4,000 kPa (40 bar; 580 psi ...

    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/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 ]

    When it is converted to the covalent red phosphorus, the density goes to 2.2–2.4 g/cm 3 and melting point to 590 °C, and when white phosphorus is transformed into the (also covalent) black phosphorus, the density becomes 2.69–3.8 g/cm 3 and melting temperature ~200 °C. Both red and black phosphorus forms are significantly harder than ...
