gasmengeling
Gasmengeling is a term used to describe a mixture of two or more gases that forms a homogeneous phase under given conditions. In practice, a gasmengeling is specified by the identities of its components and their concentrations, commonly expressed as mole or volume fractions, along with the total pressure. Under many conditions the mixture can be treated as an ideal gas, with the partial pressure of each component proportional to its mole fraction, though real-gas effects may appear at high pressures or with highly interactive gases.
Key properties of a gasmengeling depend on its constituents: density, thermal conductivity, and viscosity, as well
Production and control: gasmengelingen are prepared by mixing pure gases in calibrated flow meters or by routing
Applications and safety: gasmengelingen are used to create protective atmospheres in metallurgy and welding, inert atmospheres
