  States of Matter
The motion of solids and the reaction to external forces are described by Newton's Laws of Motion.
Scientists refer to the large scale motion of the gas as the macro scale and the individual molecular motions as the micro scale.
A plasma is a fluid, like a liquid or gas, but because of the charged particles present in a plasma, it responds to and generates electro-magnetic forces.

The gas may be dispersed in two ways, either using a stirrer or using a Garg gas-mixing valve which is described in detail Heat may be supplied or removed from the system through the jacket of the reactor or in a heat exchanger in the recycle line.
Gas is introduced at the base of the column through a gas manifold, or alternatively using a Garg gas-mixing valve, the gas may be recycled if required.
In the case of the column with variable bubble layer height, the liquid outlets are completely flooded and provided with restrictions which make it possible to adjust the heights of the bubble formation layers independently of the gas and liquid loadings.

 Gas-liquid chromatography - Wikipedia, the free encyclopedia
Gas-liquid chromatography (GLC), or simply gas chromatography (GC), is a type of chromatography in which the mobile phase is a carrier gas, usually an inert gas such as helium or nitrogen, and the stationary phase is a microscopic layer of liquid on an inert solid support, inside glass or metal tubing, called a column.
Although the carrier gas sweeps the analyte molecules through the column, this motion is inhibited by the adsorption of the analyte molecules either onto the column walls or onto packing materials in the column.
Which gas to use is usually determined by the detector being used, for example, a DID requires helium as the carrier gas.

 Gas/Liquid Separator for Microgravity
Liquid is prohibited from exiting the separator through the gas vent.
When a mixture of gas and liquid enters the separator in the volume between the cones, the liquid is forced to the outside through the holes in the spinning cones and into the cylindrical chamber.
The gas in the separator forms a distinct core at the center of the inner cone.

 Mauritz - Diffusion Research
Gas separations, based on selective permeation through polymers, were first commercially utilized by Monsanto Co. in 1977 for the recovery of H2 gas from an industrial gas stream.
The selectivity of the membrane to specific gas or liquid molecules is subject to the ability of the molecules to diffuse through the membrane.
In Figure 4, a gas or liquid molecule is depicted as moving through a membrane through the forced rearrangement of the polymer chains.

 Design of circular liquid or gas pipes software using Darcy Weisbach (Moody diagram) head loss equation
This is a common assumption in fluid mechanics and is based on the fact that a reservoir has a large surface area.
Therefore, the liquid level drops very little even if a lot of liquid flows out of the reservoir.
A reservoir may physically be a lake or a large diameter tank.

 GAS & LIQUID TRANSMISSION PIPELINES | Infrastructure
For all natural gas pipeline companies, the total investment in 1998 was $63.1 billion, from which total revenue of $13.6 billion was generated.
For liquid pipeline companies, the investment was $30.2 billion, from which revenue of $6.9 billion was generated.
At an estimated replacement cost of $643,800 per km ($1,117,000 per mi), the asset replacement value of the transmission pipeline system in the United States is $541 billion; therefore a significant investment is at risk with corrosion being the primary factor in controlling the life of the asset.

 Handheld gas, liquid sensors InTech - Find Articles
While the current technology is too cumbersome for this kind of rapid detection and response, new advances in liquid and gas phase chemical sensing may lead to the development of palm-sized sensing tools that can provide the instant detection needed.
Gas sensing done this way requires a sample of only one milliliter of gas, compared to few hundreds of milliliters for other techniques using regular multi-pass gas cells, he added.
As with the gas devices, the quantum cascade lasers vastly increase the sensitivity of liquid phase chemical detection at the surface of this waveguide.

 Gas to liquids - Wikipedia, the free encyclopedia
Gas to liquids or GTL is a refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons.
Methane-rich gases are converted into liquid fuels either via direct conversion or via syngas as an intermediate, for example using the Fischer Tropsch process.
The process may also be used for the economic extraction of gas deposits in locations where it is not economic to build a pipeline.

 GAS-Liquid Mass Transfer Application
Historically, oxygen has been the transferred gas of interest, and the "oxygen uptake rate" (OTR) is a well-known measure of the volumetric gas mass-transfer rate.
In this case, the synthesis gas is the transferred gas.
Consequently, microbubble dispersions consisting of almost 70% (by volume) gas are stable enough to be pumped from a small vessel where they are formed into the bioreactor.

 Chevron - Liquid Natural Gas
The world has enormous quantities of natural gas, but much of it is located in areas far from where the gas is needed.
LNG is natural gas that has been cooled to -260F, changing it from a gas into a liquid 1/600th its original volume.
Throughout the process of converting natural gas to and from LNG, stringent safety and security measures are employed.

 Lasers Key to Handheld Gas and Liquid Sensors
Tiny liquid phase sensors at strategic points in the city’s water mains detect the chemical as it passes and tell a computer to close down the affected pipes.
But new advances in liquid and gas phase chemical sensing being made at the Georgia Institute of Technology may lead to the development of palm-sized sensing tools that can provide the instant detection needed to stop such an attack.
For the gas sensing modules, Mizaikoff and his student Christy Charlton use a photonic band gap hollow waveguide (developed by OmniGuide),essentially a hollow, flexible tube, to both contain very small amounts of the air being sampled and assist in sensing.
