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 ]
A cold hydrogen-rich gas giant more massive than Jupiter but less than about 500 M E (1.6 M J) will only be slightly larger in volume than Jupiter. [9] For masses above 500 M E, gravity will cause the planet to shrink (see degenerate matter). [9] Kelvin–Helmholtz heating can cause a gas giant to radiate more energy than it receives from its ...
Liquid carbon dioxide can be stored at ambient temperatures, unlike Liquid air energy storage (LAES), which must keep liquid air cold at −192°C, though the CO 2 does need to be kept pressurised. Liquid CO 2 has a much higher energy density (66.7 kWh/m 3 ), than compressed air in typical to compressed-air energy storage (CAES) systems (2-6 ...
Sudarsky's classification of gas giants for the purpose of predicting their appearance based on their temperature was outlined by David Sudarsky and colleagues in the paper Albedo and Reflection Spectra of Extrasolar Giant Planets [1] and expanded on in Theoretical Spectra and Atmospheres of Extrasolar Giant Planets, [2] published before any successful direct or indirect observation of an ...
is the specific gas constant [J/(kg K)], namely the universal gas constant divided by the fluid's molecular mass; is the absolute temperature [K]. The compressibility factor is a dimensionless quantity which is equal to 1 for ideal gases and deviates from unity for increasing levels of non-ideality. [9]
Liquid nitrogen. Liquefaction of gases is physical conversion of a gas into a liquid state (condensation). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders.
Using gasifiers instead of conventional furnaces, coal and water is reduced to hydrogen gas, carbon dioxide and ash. This hydrogen gas can be used to produce electrical power In combined cycle gas turbines, CO 2 is captured, compressed to the supercritical state and injected into geological storage, possibly into existing oil fields to improve ...
The frozen gas model describes a special case of a gas that is not in equilibrium. The name "frozen gas" can be misleading. A frozen gas is not "frozen" like ice is frozen water. Rather a frozen gas is "frozen" in time (all chemical reactions are assumed to have stopped). Chemical reactions are normally driven by collisions between molecules.
