Flashcards: Gases

Carbon monoxide poisoning occurs after too much inhalation of carbon monoxide (CO).

In physics a vapor (American English spelling) or vapour (British) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature.

Propene, also known as propylene or methyl ethylene, is an unsaturated organic compound having the chemical formula C3H6.

Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen.

A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels.

Tetrafluorohydrazine or dinitrogen tetrafluoride, N2F4, is a colourless, reactive inorganic gas.

A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist.

Standard conditions for temperature and pressure are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data.

Plasma (from Greek πλάσμα, "anything formed") is one of the four fundamental states of matter, the others being solid, liquid, and gas.

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal.

Sulfur monoxide is an inorganic compound with formula SO.

Chlorotrifluorosilane is an organic gaseous compound with formula SiClF3 composed of silicon, fluorine and chlorine.

A greenhouse gas (abbrev. GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range.

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.

A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases occur and coexist at equilibrium.

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.

Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2.

Dew point is the highest temperature at which airborne water vapor will condense to form liquid dew.

Tear gas, formally known as a lachrymatory agent or lachrymator (from the Latin lacrima, meaning "tear"), is a chemical weapon that causes severe eye, respiratory, and skin irritation, pain, vomiting, and even blindness.

The kinetic theory describe a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.

Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system.

Silane is an inorganic compound with chemical formula, SiH4, making it a group 14 hydride.

Breathing is the process that moves air in and out of the lungs, or the diffusion of oxygen and carbon dioxide to and from the external environment into and out of the blood through other respiratory organs such as gills.

Fluorine azide or triazadienyl fluoride FN3 is a yellow green gas composed of nitrogen and fluorine with formula FN3.

("Towngas" redirects here. Towngas may also refer to the brand name of The Hong Kong and China Gas Company.) Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system.

Clathrate hydrates, or gas clathrates, gas hydrates, clathrates, hydrates, etc.

Arsine is an inorganic compound with the formula AsH3.

Diacetylene (also known as butadiyne) is the organic compound with the formula (C2H)2.

Germanium tetrafluoride (GeF4) is a chemical compound of germanium and fluorine.

In thermodynamics, the volume of a system is an important extensive parameter for describing its thermodynamic state.

In statistics the Maxwell–Boltzmann distribution is a particular probability distribution named after James Clerk Maxwell and Ludwig Boltzmann.

Chloryl fluoride is the chemical compound with the formula ClO2F.

Chlorine gas poisoning is illness resulting from the effects of exposure to chlorine beyond the threshold limit value.

Disulfur monoxide or sulfur suboxide is an inorganic compound with formula S2O.

Vacuum is space void of matter.

Cyclopropene is an organic compound with the formula C3H4.

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.

In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect, Kelvin–Joule effect, or Joule–Thomson expansion) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is forced through a valve or porous plug while kept insulated so that no heat is exchanged with the environment.

In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve.

An inert gas is a gas which does not undergo chemical reactions under a set of given conditions.

Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.

In chemistry, absorption is a physical or chemical phenomenon or a process in which atoms, molecules or ions enter some bulk phase – gas, liquid or solid material.

Fluoromethane, also known as methyl fluoride, Freon 41, Halocarbon-41 and HFC-41, is a non-toxic, liquefiable, and flammable gas at standard temperature and pressure.

Trimethylborane (TMB) is a toxic, pyrophoric gas with the formula B(CH3)3 (which can also be written as Me3B, with Me representing methyl).

Selenoyl fluoride, selenoyl difluoride, selenium oxyfluoride, or selenium dioxydifluoride is a chemical compound with the formula SeO2F2.
