In the ASHRAE book Heat and Cold: Mastering the Great Indoors, the historical use of carbon dioxide as a refrigerant is explained as follows: Carbon dioxide (also known as carbonic acid gas and carbonic anhydride) was first proposed as a refrigerant for vapor-compression systems by Alexander Twining, who mentioned it in his 1850 British patent .
Carbonic anhydride may refer to: Carbon dioxide, the acidic oxide of carbonic acid; Dicarbonic acid, the monoanhydride of carbonic acid using two molecules; 1,3-Dioxetanedione, the dianhydride of carbonic acid using two molecules; 1,3,5-Trioxanetrione, the dianhydride of carbonic acid …
Using the phase diagram for CO2 what phase is carbon dioxide in at -20C and 1 ATM pressure? The triple point of Carbon Dioxide is 216.55 K (−56.60 °C) and 517 kPa (5.10 atm).

Carbonic anhydrase is one of the fastest enzymes, and its rate is typically limited by the diffusion rate of its substrates. Typical catalytic rates of the different forms of this enzyme ranging between 10 4 and 10 6 reactions per second.
The hydration equilibrium constant of carbonic acid is =  [()] = × − (at 25 °C). Hence, the majority of the carbon dioxide is not converted into carbonic acid, but remains as CO 2 molecules, not affecting the pH.
Carbon Dioxide. Carbon dioxide is thermostable, dissociating into carbon monoxide and oxygen only at a temperature above 2000°C. The compound is noticeably soluble in water, forming solutions of 0.335 percent (by weight) at 0°C and 0.169 percent at 20°C; it partially reacts with water to form carbonic acid …
Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.
