  Gas -   (Site not responding. Last check: 2007-09-17)
A gas is one of the four main phases of matter (after solid and liquid, and followed by plasma), that subsequently appear as a solid material is subjected to increasingly higher temperatures.
The thermodynamic state of a gas is characterized by its volume, its temperature, which is determined by the average velocity or kinetic energy of the molecules, and its pressure, which is determined by the average velocity and density or number of molecules.
The word "gas" was invented by Jan Baptist van Helmont as a phonetic spelling of the Flemish pronunciation of the Greek word "chaos".

 Gas Summary
As this happens the pressure that the gas is exerting on the walls of the chamber decreases as there are fewer molecules colliding with a given area of the containers walls.
The ideal gas equation can be written as PV = nRT where P is the pressure, V is the volume, n is the number of moles of gas, T is the temperature of the gas (in Kelvin), and R is the universal gas constant.
This law states that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of the gas.

Because of this increased kinetic energy, gas atoms and molecules tend to bounce off of any containing surface and off one another, the more powerfully as the kinetic energy is increased.
A gas that is ionized (or even partially ionized) becomes a plasma, the fourth state of matter because its properties are quite different to solids, liquids and gases.
The word "gas" was probably coined by a Flemish chemist as a re-spelling of his pronunciation of the Greek word chaos.

 Piston - LoveToKnow 1911
The piston in gas, oil and air engines has a similar function, but in a pump, instead of imparting motion, it has motion imparted to it by some prime-mover.
In every case the piston must fit the cylinder so accurately that as little as possible of the working fluid, whether it be steam, gas or water, can escape past it, packing of various forms being commonly placed round its periphery in order to secure this fit.
In music, the valves which in certain wind instruments, such as the cornet, enable the player to increase the length of the air-column and thus lower the note produced, are known as pistons.

 Volcano - Facts, Information, and Encyclopedia Reference article
A volcano is a geological landform (usually a mountain) where magma (rock of the Earth's interior made molten or liquid by extremely high temperatures along with a reduction in pressure and/or the introduction of water or other volatiles) erupts through the surface of the planet.
Water vapor is typically the most abundant volcanic gas, followed by carbon dioxide and sulfur dioxide.

 xenon Information Center - xenon
A colorless, very heavy, odorless noble gas, xenon occurs in the earth's atmosphere in trace amounts and was part of the first noble gas lucy lawless xena compound synthesized.
This gas is most widely and most famously used in light-emitting devices called Xenon flash lamps, which are used in photographic flashes, stroboscopic lamps, to excite the active medium in lasers which then generate coherent light, in bactericidal lamps (rarely), and in certain dermatological uses.
There is a danger associated with any heavy gas in large quantities: it may sit invisibly in a container, and if a person enters a container filled with an odorless, colorless gas, they may find themselves breathing it unknowingly.

 William Henry - LoveToKnow 1911
He began to study medicine at Edinburgh in 1795, taking his doctor's degree in 1807, but ill-health interrupted his practice as a physician, and he devoted his time mainly to chemical research, especially in regard to gases.
Trans., 1803) describes experiments on the quantity of gases absorbed by water at different temperatures and under different pressures, the conclusion he reached ("Henry's law") being that "water takes up of gas condensed by one, two or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, andc.
the volume absorbed under the common pressure of the atmosphere." Others of his papers deal with gas-analysis, fire-damp, illuminating gas, the composition of hydrochloric acid and of ammonia, urinary and other morbid concretions, and the disinfecting powers of heat.

It is absolutely necessary to define the standard reference conditions of temperature and pressure when expressing a gas volume or a volumetric flow rate because the volume of a gas varies with the temperature and pressure of the gas.
In technical diving, the maximum operating depth (MOD) of a breathing gas is the depth at which the partial pressure of oxygen (ppO2) of the gas mix exceeds a safe limit.
This safe limit varies depending on the diver training agency, the level of underwater exertion planned and the planned duration of the dive, but is normally in the range of 1.2 to 1.6 bar.

 Entropy - Article from FactBug.org - the fast Wikipedia mirror site
To illustrate this, consider a gas enclosed in a piston chamber, whose volume may be changed by moving the piston.
For example, a microstate of a classical ideal gas is specified by the positions and momenta of all the atoms, which range continuously over the real numbers.
The entropy in such a state would be that of a classical ideal gas plus contributions from molecular rotations and vibrations, which may be determined spectroscopically.

 Turbo Engine - Wikicars
Exhaust gas directed through the wastegate is not used to spin the shaft assembly.
To manage the upper-deck air pressure, the turbocharger's exhaust gas flow is regulated with a wastegate that bypasses excess exhaust gas entering the turbocharger's turbine.
Diesel engines are usually much kinder to turbos because their exhaust gas temperature is much lower than that of gasoline engines and because most operators allow the engine to idle and do not switch it off immediately after heavy use.
