  3. Liquid hydrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_hydrogen

    Liquid hydrogen also has a much higher specific energy than gasoline, natural gas, or diesel. [12] The density of liquid hydrogen is only 70.85 kg/m 3 (at 20 K), a relative density of just 0.07. Although the specific energy is more than twice that of other fuels, this gives it a remarkably low volumetric energy density, many fold lower.

    A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875). Ref. SMI uses temperature scale ITS-48. No conversion was done, which should be of little consequence however.

    en.wikipedia.org/wiki/List_of_conversion_factors

    Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).

    en.wikipedia.org/wiki/Liquefaction_of_gases

    Liquid nitrogen Liquefaction of gases is physical conversion of a gas into a liquid state ( condensation ). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders .

    Using too much liquid: start with a little liquid (whether it’s cream or milk) and gradually add more if needed. No matter what went wrong, there are ways to turn your watery mashed potatoes around.

  8. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg -1 ⋅K -1 and heat of vaporization of 200 kJ⋅kg -1 makes it extremely useful in a wide range of applications ...
