A scientific term referring to the density of a vapor relative to that of hydrogen or air, often used in chemistry and physics to describe how heavy a gas or vapor is compared to a standard.

  1. Relative density of a gasC2formal

    The density of a vapor or gas relative to that of a standard gas, typically hydrogen or air, at the same temperature and pressure.

    zh相对蒸气密度

    • The vapor density of carbon dioxide is approximately 1.5 times that of air.
    • Chemists use vapor density to identify unknown gases.
    • Calculating vapor density helps in determining the molecular weight of a substance.
