  2. Poynting effect - Wikipedia

    en.wikipedia.org/wiki/Poynting_effect

    is the liquid/vapor's gas constant is the temperature is the total pressure (vapor pressure + non-condensable gas) A common example is the production of the medicine Entonox, a high-pressure mixture of nitrous oxide and oxygen. The ability to combine N 2 O and O

  3. Low-temperature distillation - Wikipedia

    en.wikipedia.org/wiki/Low-temperature_distillation

    Two separate volume flows, a hot evaporator flow and a cool condenser flow, with different temperatures and vapor pressures, are sprayed in a combined pressure chamber, where non-condensable gases are continuously removed. [3] [4] As the vapor moves to a partial pressure equilibrium, part of the water from the hot stream evaporates. [5]

    en.wikipedia.org/wiki/Thermodynamic_activity

    The relative activity of a species i, denoted a i, is defined [4] [5] as: = where μ i is the (molar) chemical potential of the species i under the conditions of interest, μ o i is the (molar) chemical potential of that species under some defined set of standard conditions, R is the gas constant, T is the thermodynamic temperature and e is the exponential constant.

  5. List of gases - Wikipedia

    This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...

  6. Oil shale gas - Wikipedia

    en.wikipedia.org/wiki/Oil_shale_gas

    Oil shale gas (also: retort gas or retorting gas) is a synthetic non-condensable gas mixture produced by oil shale thermal processing . Although often referred to as shale gas, it differs from the natural gas produced from shale , which is also known as shale gas.

  7. Solution (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Solution_(chemistry)

    If the solvent is a gas, only gases (non-condensable) or vapors (condensable) are dissolved under a given set of conditions. An example of a gaseous solution is air (oxygen and other gases dissolved in nitrogen). Since interactions between gaseous molecules play almost no role, non-condensable gases form rather trivial solutions.
