  2. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N 2 O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. [4]

  3. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    However, the liquid–vapor boundary terminates in an endpoint at some critical temperature T c and critical pressure p c. This is the critical point . The critical point of water occurs at 647.096 K (373.946 °C; 705.103 °F) and 22.064 megapascals (3,200.1 psi; 217.75 atm; 220.64 bar).

  4. Supercritical fluid - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid

    The surface pressure is 9.3 megapascals (1,350 psi) and the surface temperature is 735 K (462 °C; 863 °F), above the critical points of both major constituents and making the surface atmosphere a supercritical fluid. [13]

  5. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    A typical phase diagram.The solid green line applies to most substances; the dashed green line gives the anomalous behavior of water. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. [1]

  6. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    Some other gases exhibit this phase change if the ambient temperature is low enough; this includes ethylene (R1150), carbon dioxide (R744), ethane (R170), nitrous oxide (R744A), and sulfur hexafluoride; however, these can only be liquefied under pressure if kept below their critical temperatures which are 9 °C for C 2 H 4 ; 31 °C for CO 2 ...

  7. Naturally aspirated engine - Wikipedia

    en.wikipedia.org/wiki/Naturally_aspirated_engine

    Nitrous oxide is 36.3% available oxygen by mass after it decomposes as compared with atmospheric air at 20.95%. Nitrous oxide also boils at −127.3 °F (−88.5 °C) at atmospheric pressures and offers significant cooling from the latent heat of vaporization, which also aids in increasing the overall air charge density significantly compared ...

  8. Nitrous oxide engine - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide_engine

    A nitrous oxide engine, or nitrous oxide system (NOS) is an internal combustion engine in which oxygen for burning the fuel comes from the decomposition of nitrous oxide, N 2 O, as well as air. The system increases the engine's power output by allowing fuel to be burned at a higher-than-normal rate, because of the higher partial pressure of ...

  9. Whipped-cream charger - Wikipedia

    en.wikipedia.org/wiki/Whipped-cream_charger

    A box of chargers, showing their foil sealed ends that release the gas after being punctured. The cylinders are about 6.3 centimetres (2 + 1 ⁄ 2 in) long by 1.8 cm (3 ⁄ 4 in) wide, with a volume of 10 cubic centimetres (0.6 cu in) and capacity for most brands of 8 grams (1 ⁄ 4 oz) of pressurized N 2 O.
