Natural gas cannot be utilized in the form it is obtained as it contains many impurities that need to be removed, so that, only methane remains. Refinement process leads to many other byproducts such as propane, butane and pentane along with sulfur, CO2, water vapor with traces of N2 and helium gases. In brief: D...
The Influence of Partial Pressure Difference and Supersaturation on the Frost Formation during the Cooling of Gas-Vapor-Mixtures in Counterflow Heat ExchangersThis chapter describes the influence of partial pressure difference and supersaturation on the frost formation during the cooling of gas鈥搗apor-...
In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and press at which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be distinguished;...
"Me and my family are going down to Florida and we're currently thinking about driving there, which is like a 24-hour drive, and we're thinking that'll be $700-800 worth of gas," said Willy Black, of Eden Prairie. Even though the summer blend is more expensive, it actually contains...
The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the earth. A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse ...

In addition to the SI (Système Internationale) unit, the joule, energy can measured in calories, British thermal units (Btu), tonnes of oil equivalent (toe), tonnes of coal equivalent (tce), kilowatt-hours (kWh), and in physical units (e.g., cubic meters of gas, barrels of oil). ...
Sublimationis the process by which molecules go directly from solid into the vapor or gas phase. Depositionis the process by which molecules go directly from the gas phase into the solid phase. Deposition chemistry occurs when molecules settle out of the gas phase and into the solid phase. ...

Nitrogen and argon are extracted from sea water ( in vacuo) and separated from water vapor, carbon dioxide and oxygen. The residual nitrogen-argon mixture is swept over a thermal conductivity detector with a carrier gas of the same composition, except for having a slightly different argon mole ...
