Precise pressure-volume-temperature measurements on corrosive gases are dependent on a sensitive yet rugged pressure transducer.

These scientists are convinced that a telescope unclouded by the earth's gases will go a long way toward bolstering or destroying cosmic theories.

Most amphibians, however, are able to exchange gases with the water or air via their skin.

Allotropes are typically more noticeable in non-metals ( excluding the halogens and the noble gases ) and metalloids.

The simplest alkenes, ethene, propene and butene are gases.

In reality, gases are composed of molecules which collide with one another and solid objects.

The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes.

The gases can be carried hundreds of kilometers in the atmosphere before they are converted to acids and deposited.

Wet removal of both gases and aerosols are both of importance for wet deposition.

Further improvements are achievable by catalytic after-burning devices ( such as catalytic converters ) or by the simple partial return of the exhaust gases into the combustion process.

All but a few of the most inert elements, such as noble gases and noble metals, are usually found on Earth in chemically combined form, as chemical compounds.

Similarly, the halogens and the noble gases are nonmetals, viewed in the broader sense.

Most of the elements are solids at conventional temperatures and atmospheric pressure, while several are gases.

Since several elements are gases at commonly encountered temperatures, their densities are usually stated for their gaseous forms ; when liquefied or solidified, the gaseous elements have densities similar to those of the other elements.

Materials, such as solids, liquids and gases, are composed of molecules separated by empty space.

The atoms in molecules, crystals, metals and diatomic gases — indeed most of the physical environment around us — are held together by chemical bonds, which dictate the structure and the bulk properties of matter.

Polysilicon may be grown directly with doping, if gases such as phosphine, arsine or diborane are added to the CVD chamber.

The energy source is intended to generate a plasma in which the gases are broken down and more complex chemistries occur.

Since the electrical conductivity is low, gases are dielectrics or insulators.

Elements are trying to reach the low-energy noble gas configuration, and therefore alkali metals and halogens will donate and accept one electron, respectively, and the noble gases themselves are chemically inactive.

Since most of the atmosphere's quantity of such triatomic gases is contained within the troposphere, this portion of the atmosphere is readily heated by the earth's radiation.

Between 1886 and 1892 he published a series of papers on the foundations of the kinetic theory of gases, the fourth of which contained what was, according to Lord Kelvin, the first proof ever given of the Waterston-Maxwell theorem ( equipartition theorem ) of the average equal partition of energy in a mixture of two gases.

The potential damage is primarily a function of the total amount of fuel burned in the event ( total energy available ), the maximum flame velocity that is achieved, and the manner in which the expansion of the combustion gases is contained.

Assuming the magma that formed Tharsis contained carbon dioxide ( CO < sub > 2 </ sub >) and water vapor in percentages comparable to that observed in Hawaiian basaltic lava, then the total amount of gases released from Tharsis magmas could have produced a 1. 5-bar CO < sub > 2 </ sub > atmosphere and a global layer of water 120 m thick.

This may include a self contained breathing apparatus ( SCBA ), protective headgear and the use of explosion proof lighting ( to prevent igniting any gases ).

The gain medium of the laser, as suggested by its name, is a mixture of helium and neon gases, in approximately a 10: 1 ratio, contained at low pressure in a glass envelope.

Gas exchange is a process in biology where gases contained in an organism and atmosphere transfer or exchange.

In human gas-exchange, gases contained in the blood of human bodies exchange with gases contained in the atmosphere.

After the eruption, Spirit Lake contained highly toxic water with volcanic gases seeping up from the lake bed.

This system was made up of an integral helium and hydrogen start tank, which contained the hydrogen and helium gases for starting and operating the engine.

Gas contained in coal bed methane is mainly methane and trace quantities of ethane, nitrogen, carbon dioxide and few other gases.

For example, smoke explosion is a very violent combustion of unburned gases contained in the smoke created by a sudden fresh air input ( oxidizer input ).

The demand for pneumatic drills was driven especially by miners and tunnelers because steam engines required fires in order to operate and the ventilation in mines and tunnels was inadequate to vent the fires ' fumes ; there was also no way to convey steam over long distances ( e. g., from the surface to the bottom of a mine ); furthermore, mines and tunnels occasionally contained flammable explosive gases such as methane.

Their contained gases have not been able to escape through the thick layer of strata, beneath which they were injected.

The reason an air horn can function as an effective refrigerant is that the gases contained within the device are highly pressurized, which means that the object also acts as a pressure vessel.

In these gases the mean free path of molecules is bigger than the receptacle where the gas is contained.

The remaining non-purgeable CO < sub > 2 </ sub > gas ( NPOC ) contained in the liquid aliquot is then oxidized releasing the gases.

When it first formed, Earth's atmosphere may have contained more greenhouse gases.

* Nikola Tesla was famous for developing the AC motor, the bifilar coil, various devices that used rotating magnetic fields, the alternating current polyphase power distribution systems, the fundamental devices of systems of wireless communication ( legal priority for the invention of radio ), radio frequency oscillators, devices for voltage magnification by standing waves, robotics, logic gates for secure radio frequency communications, devices for x-rays, apparatus for ozone generation, devices for ionized gases, devices for high field emission, devices for charged particle beams, methods for providing extremely low level of resistance to the passage of electrical current, means for increasing the intensity of electrical oscillations, voltage multiplication circuitry, devices for high voltage discharges, devices for lightning protection and VTOL aircraft.

An aerostat ( From Greek ἀήρ aer ( air ) + στατός statos ( standing ) through French ) is a craft that remains aloft primarily through the use of buoyant lighter than air gases, which impart lift to a vehicle with nearly the same overall density as air.
