In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure , a substance with high volatility is more likely to exist as a vapour , while a substance with low volatility is more likely to be a liquid or solid .
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold , upholstered furniture , arts and crafts supplies, dry cleaned clothing, and cleaning supplies . [ 2 ]
Volatility (chemistry), a measuring tendency of a substance or liquid to vaporize easily Volatile organic compounds, organic or carbon compounds that can evaporate at normal temperature and pressure Volatile anaesthetics, a class of anaesthetics which evaporate or vaporize easily
Volatile acid concentration can be used to detect adulteration of butter with less expensive fats. Butterfat has uncommonly high levels of volatile butyric and caproic acids, and mixing with fats from other sources dilutes the volatile acids. A measurement of the volatile acids is known as the Reichert Meissel value. [19] [20] [21]
A volatile corrosion inhibitor (VCI) is a material that protects metals from corrosion. Corrosion inhibitors are chemical compounds that can decrease the corrosion rate of a material, typically a metal or an alloy .
A secondary organic aerosol (SOA) is a molecule produced via oxidation over several generations of a parent organic molecule. [1] In contrast to primary organic aerosols, which are emitted directly from the biosphere, SOAs are either formed via homogeneous nucleation through the successive oxidation of gas-phase organic compounds, or through condensation on pre-existing particles.
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
Non-methane volatile organic compounds (NMVOCs) are a set of organic compounds that are typically photochemically reactive in the atmosphere—marked by the exclusion of methane. [1] NMVOCs include a large variety of chemically different compounds, such as benzene , ethanol , formaldehyde , cyclohexane , 1,1,1-trichloroethane and acetone . [ 2 ]
