Gases were rarely a hazard, but spontaneous combustion of coal dust was a potential problem.

Gases ( other than air ) in coal mines in England were collectively known as " damps ".

Gases were frequently mixed, for example white star was the name given to a mixture of equal volumes of chlorine and phosgene, the chlorine helping to spread the denser but more toxic phosgene.

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

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.

On August 10, 2008, a massive explosion occurred at the Sunrise Propane Industrial Gases propane facility just southwest of the Toronto-Downsview Airport.

On August 10, 2008, just before 4 a. m., massive explosions occurred at the Sunrise Propane Industrial Gases propane facility, at 54 Murray Rd., located immediately north-east of the intersection of Keele Street and Wilson Avenue.

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

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.

The Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, usually called the Geneva Protocol, is a treaty prohibiting the first use of chemical and biological weapons.

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

* 1925 Geneva protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare

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

Signed on June 17, 1925 and entering into force on February 8, 1928, it permanently bans the use of all forms of chemical and biological warfare in its single section, entitled Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare.

Final Guidance, “ Federal Greenhouse Gas Accounting and Reporting ”-This is the final notice to agencies to help them comply with an annual acoounting for Greenhouse Gases as required by Executive Order # 13514.

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 are removed for various reasons.

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

Gases, on the other hand, all have the properties ( 1 ), ( 2 ), and ( 3 )( a )( α ) and ( 3 )( b )( α ).

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

* Gases: nitric oxide ( NO ), carbon monoxide ( CO ) and hydrogen sulphide ( H2S ) which can diffuse both through cytosol and across cellular membranes.

Gases can also be sequestered by adsorption, where fine particles in the regolith capture gas which adheres to the surface particles.

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

* James H. Jeans's The Dynamical Theory of Gases is published in Cambridge.

Gas is one of the phases of matter ( Gases, or Gasses Plural ) along with solid and liquid.

His scientific reputation is grounded in the monographs The Dynamical Theory of Gases ( 1904 ), Theoretical Mechanics ( 1906 ), and Mathematical Theory of Electricity and Magnetism ( 1908 ).

* Gases or gas mixtures, often carbon dioxide is used to induce unconsciousness and then death.

Gases used in diving have very different thermal conductivity ; trimix conducts heat more than air and argon conducts less heat than air hence the reason many trimix divers inflate their drysuits with argon.

Gases including oxygen have high solubility in Fluorinert, as fluorocarbons exhibit weak cohesive intermolecular forces.

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

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