  • Volatility (chemistry)
    Volatility (chemistry)
    In chemistry and physics, volatility is the tendency of a substance to vaporize. Volatility is directly related to a substance's vapor pressure. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure.The term is primarily...

    , a measure of the tendency of a substance to vaporize
  • Relative volatility
    Relative volatility
    Relative volatility is a measure comparing the vapor pressures of the components in a liquid mixture of chemicals. This quantity is widely used in designing large industrial distillation processes. In effect, it indicates the ease or difficulty of using distillation to separate the more volatile...

    , a measure of vapor pressures of the components in a liquid mixture
  • Volatiles
    Volatiles
    In planetary science, volatiles are that group of chemical elements and chemical compounds with low boiling points that are associated with a planet's or moon's crust and/or atmosphere. Examples include nitrogen, water, carbon dioxide, ammonia, hydrogen, and methane, all compounds of C, H, O...

    , a group of compounds with low boiling points that are associated with a planet's or moon's crust and/or atmosphere
  • Volatile organic compound
    Volatile organic compound
    Volatile organic compounds are organic chemicals that have a high vapor pressure at ordinary, room-temperature conditions. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and...

    s, organic compounds that can evaporate at normal temperature and pressure, and are often regulated by governments
  • Volatile anaesthetics, a class of anaesthetics which evaporate easily
  • Volatile substance abuse, the abuse of household inhalants containing volatile compounds
  • Volatile oil, also known as essential oil, an oil derived from plants with aromatic compounds used in cosmetics and flavoring
