Gases behave in a similar way over a wide variety of conditions because to a good approximation they all have molecules which are widely spaced, and nowadays the equation of state for an ideal gas is derived from kinetic theory.

" Gases are produced which result in " a characteristic ' blow ,' exchanging the material from deep underground for the matter on the surface above it.

Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure.

Gases from hot springs are composed mostly of steam and carbon dioxide, with minor amounts of other gases.

In 1999, reports emerged that the US Industrial gases company Praxair-a 1992 spun off from Linde AG's US division, ' Union Carbide Industrial Gases ' - are in possible merger discussions with BOC Group.

Gases are more difficult to measure than liquids, as measured volumes are highly affected by temperature and pressure.

Gases typically used are helium, argon, nitrogen, neon and ( for short periods of time, as it destroys the oxide coating on the cathode ) hydrogen.

Gases with an H < sub > 2 </ sub > S content of over 25 % are suitable for the recovery of sulfur in straight-through Claus plants while alternate configurations such as a split-flow set up or feed and air preheating can be used to process leaner feeds.

Gases containing ammonia, such as the gas from the refinery's sour water stripper ( SWS ), or hydrocarbons are converted in the burner muffle.

Gases containing H < sub > 2 </ sub > S or both H < sub > 2 </ sub > S and CO < sub > 2 </ sub > are commonly referred to as sour gases or acid gases in the hydrocarbon processing industries.

Gases are removed for various reasons.

Gases like CO < sub > 2 </ sub > and green gas are stored in liquid form and require heat in order to vaporize.

His interest in this branch of physics and chemistry dates back at least as far as 1874, when he discussed the " Latent Heat of Liquid Gases " before the British Association.

Gases and waves do not behave in the same way when encountering turns.

Their patent request was granted in London on June 12, 1854, and published in London's Morning Journal under the title " Specification of Eugene Barsanti and Felix Matteucci, Obtaining Motive Power by the Explosion of Gases ", as documented by the Fondazione Barsanti e Matteucci.

* Class 2 Gases, including compressed, liquified and dissolved under pressure gases and vapors

Gases will always flow from a region of higher partial pressure to one of lower pressure ; the larger this difference, the faster the flow.

Gases at high pressure can have a density exceeding that of some solids.

Gases can be refined in this way as well, by being cooled and / or compressed until they liquefy.

Gases such as hydrogen chloride can be acids as well.

In 1815, he published Mémoire sur les masses relatives des molécules des corps simples, ou densités présumées de leur gaz, et sur la constitution de quelques-uns de leur composés, pour servir de suite à l ' Essai sur le même sujet, publié dans le Journal de Physique, juillet 1811 (" Note on the Relative Masses of Elementary Molecules, or Suggested Densities of Their Gases, and on the Constituents of Some of Their Compounds, As a Follow-up to the Essay on the Same Subject, Published in the Journal of Physics, July 1811 ") (), about gas densities.

Gases dissolve, diffuse, and react according to their partial pressures, and not according to their concentrations in gas mixtures or liquids.

Gases will preferentially condense onto pre-existing surfaces ( e. g. aerosol particles ), which is known as heterogeneous nucleation.

Gases passing through an ideal gas turbine undergo three thermodynamic processes.

Gases then pass from the diffuser to a combustion chamber, or similar device, where heat is added.

See the page Regulation of Greenhouse Gases Under the Clean Air Act for further information.

Gases from the burning powder pressurize and expand the case to seal it against the chamber wall.

While all real fluids are compressible, a flow problem is often considered incompressible if the density changes in the problem have a small effect on the outputs of interest.

Transonic, supersonic, and hypersonic flows are all compressible.

In other words, the enumerable first n bits of Omega are highly compressible in the sense that they are limit-computable by a very short algorithm ; they are not random with respect to the set of enumerating algorithms.

All fluids are compressible to some extent, that is, changes in pressure or temperature will result in changes in density.

For compressible working fluids, multiple turbine stages are usually used to harness the expanding gas efficiently.

If these confining layers are composed of compressible silt or clay, the loss of water to the aquifer reduces the water pressure in the confining layer, causing it to compress from the weight of overlying geologic materials.

Also, these papers are extremely thin and compressible, allowing for thin, narrowed limbs as in the case of insect models.

Also, the low attractive forces in fluorocarbon liquids make them compressible and gas soluble while smaller fluorocarbons are extremely volatile.

Peat deposits also pose major difficulties to builders of structures, roads, and railways, as they are highly compressible under even small loads.

These knives are set into the slots and covered in a compressible material, typically foam rubber, the function of which is the ejection of the cut puzzle pieces.

The most distinct differences between the compressible and incompressible flow models are that the compressible flow model allows for the existence of shock waves and choked flow.

However, in the many cases dealing with gases ( especially at higher velocities ) and those cases dealing with liquids with large pressure changes, the significant variations in density can occur, and the flow should be analysed as a compressible flow if accurate results are to be obtained.

Two of the most distinctive phenomena which occur in compressible are the possibility of choked flow ( see Internal Flows ) and the presence of acoustic waves, which may also be referred to as either compression or expansion waves, depending on whether they lead to an increase or decrease in pressure.

Shock waves are one of the most common examples of compressible flow phenomena.

For Mach numbers greater than about 0. 3, density changes are significant, and the flow should be considered compressible for an accurate representation of reality.

As a floating object rises or falls, the forces external to it change and, as all objects are compressible to some extent or another, so does the object's volume.

These bolts, usually tension control bolts or compressible washer tension indicating type bolts, are tensioned to a minimum required amount to generate large enough friction forces between the faying surfaces such that the shear ( or tension ) load is transferred by the structural members and not by the bolts ( in shear ) and the connection plates ( in bearing ).

Most technologies described as " new media " are digital, often having characteristics of being manipulated, networkable, dense, compressible, and interactive.

Compounders or accelerators are energized when you over pull on the working string and compress a compressible fluid through a few feet of stroke distance and at the same time activate the fishing jar.
