  2. Gas - Wikipedia

    en.wikipedia.org/wiki/Gas

    An ideal gas is a simplified "real gas" with the assumption that the compressibility factor Z is set to 1 meaning that this pneumatic ratio remains constant. A compressibility factor of one also requires the four state variables to follow the ideal gas law .

  3. Natural gas - Wikipedia

    en.wikipedia.org/wiki/Natural_gas

    Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.

  4. Gaslighting - Wikipedia

    en.wikipedia.org/wiki/Gaslighting

    Google Trends topic searches for "Gaslighting" began a substantial increase in 2016. [1]Gaslighting is the manipulation of someone into questioning their own perception of reality.

  5. Ideal gas - Wikipedia

    en.wikipedia.org/wiki/Ideal_gas

    An ideal gas is a theoretical gas composed of many randomly moving point particles that are not subject to interparticle interactions. [1] The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics.

  6. Kinetic theory of gases - Wikipedia

    en.wikipedia.org/wiki/Kinetic_theory_of_gases

    The mathematical similarities between the expressions for shear viscocity, thermal conductivity and diffusion coefficient of the ideal (dilute) gas is not a coincidence; It is a direct result of the Onsager reciprocal relations (i.e. the detailed balance of the reversible dynamics of the particles), when applied to the convection (matter flow ...

    TGOR – total gas oil ratio (GOR uncorrected for gas lift gas present in the production fluid [citation needed]) TH – tubing hanger; THCP – tubing hanger crown plug; Thr/Th# – thruster ('#'- means identification letter/number of the equipment, e.g. thr3 or thr#3 means "thruster no. 3" [citation needed]) THD – tubing head; THERM ...

  8. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.

  9. Gas constant - Wikipedia

    en.wikipedia.org/wiki/Gas_constant

    The gas constant occurs in the ideal gas law: = = where P is the absolute pressure, V is the volume of gas, n is the amount of substance, m is the mass, and T is the thermodynamic temperature. R specific is the mass-specific gas constant. The gas constant is expressed in the same unit as molar heat.
