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 [123] (listed as E number E290), US, [124] Australia and New Zealand [125] (listed by its INS number 290). A candy called Pop Rocks is pressurized with carbon dioxide gas [126] at about 4,000 kPa (40 bar; 580 psi ...

In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of three main greenhouse gases in the atmosphere of Earth. The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.04%) in 2024. [1]

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.
Subliming dry ice pellet, with white frost on the surface. Dry ice colloquially 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.
Jo Denman and Tessa Parry-Wingfield formed a close friendship after they were both diagnosed with a rare form of cancer which resulted in them each having an eye removed
Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
