    For a given mass of gas at constant temperature, the volume varies inversely with the pressure. Bragg's law bridge A chemical bond between valence electrons, or an atom or unbranched chain of atoms connecting two different parts of the same molecule; i.e. an intramolecular bond linking different moieties or functional groups.

  3. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    Density (volumetric mass density or specific mass) is a substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho ), although the Latin letter D can also be used.

    Seam – a unit of mass or volume; Seer – a unit of mass or volume; Toise – a unit of area, length, or volume; Tub – usually a unit of mass, but sometimes a unit of volume; Uncia – an ancient Roman unit of length, mass, or volume; Wey – a unit of mass or volume; Winchester measure – a system of volume measurement

    Phase space volume is conserved. liquid One of four classical states of matter having a definite volume but no fixed shape. liquid crystal (LC) A state of matter which has properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal ...

  6. Bushel - Wikipedia

    en.wikipedia.org/wiki/Bushel

    The Winchester bushel is the volume of a cylinder 18.5 in (470 mm) in diameter and 8 in (200 mm) high, which gives an irrational number of approximately 2150.4202 cubic inches. [4] The modern American or US bushel is a variant of this, rounded to exactly 2150.42 cubic inches, less than one part per ten million less. [5]

  7. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    In terms of density, m = ρV, where ρ is the volumetric mass density, V is the volume occupied by the mass. This energy can be released by the processes of nuclear fission (~ 0.1%), nuclear fusion (~ 1%), or the annihilation of some or all of the matter in the volume V by matter–antimatter collisions (100%). [citation needed]

  8. Volume - Wikipedia

    en.wikipedia.org/wiki/Volume

    Some SI units of volume to scale and approximate corresponding mass of water. To ease calculations, a unit of volume is equal to the volume occupied by a unit cube (with a side length of one). Because the volume occupies three dimensions, if the metre (m) is chosen as a unit of length, the corresponding unit of volume is the cubic metre (m 3).

  9. Litre - Wikipedia

    en.wikipedia.org/wiki/Litre

    Some SI units of volume to scale and approximate corresponding mass of water. A litre is a cubic decimetre, which is the volume of a cube 10 centimetres × 10 centimetres × 10 centimetres (1 L ≡ 1 dm 3 ≡ 1000 cm 3). Hence 1 L ≡ 0.001 m 3 ≡ 1000 cm 3; and 1 m 3 (i.e. a cubic metre, which is the SI unit for volume) is exactly 1000 L.
