Jets of 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).

Major producers worldwide include Dow Chemical at 2 million tonnes annually (Mt/year), calculated as HCl gas, Georgia Gulf Corporation, Tosoh Corporation, Akzo Nobel, and Tessenderlo at 0.5 to 1.5 Mt/year each. Total world production, for comparison purposes expressed as HCl, is estimated at 20 Mt/year, with 3 Mt/year from direct synthesis, and ...
At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m 3, about 4.5 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [50] As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. [ 51 ]
An ampule of nitrogen oxide vapor: brown nitrogen dioxide and colorless dinitrogen tetroxide, in equilibrium. In physics, a vapor (American English) or vapour (Commonwealth English; see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature, [1] which means that the vapor can be condensed to a liquid by increasing the pressure on it without ...

The aerosol spray canister invented by USDA researchers, Lyle Goodhue and William Sullivan.. The concepts of aerosol probably go as far back as 1790. [1] The first aerosol spray can patent was granted in Oslo in 1927 to Erik Rotheim, a Norwegian chemical engineer, [1] [2] and a United States patent was granted for the invention in 1931. [3]
Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
CO may be emitted from tobacco smoke and generated from malfunctioning fuel burning stoves (wood, kerosene, natural gas, propane) and fuel burning heating systems (wood, oil, natural gas) and from blocked flues connected to these appliances. [8] Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. [9] [8] [10]
