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 .
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]
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.
Steam distillation is a separation process that consists of distilling water together with other volatile and non-volatile components. The steam from the boiling water carries the vapor of the volatiles to a condenser; both are cooled and return to the liquid or solid state, while the non-volatile residues remain behind in the boiling container.
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants.Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove.
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 ]
In igneous petrology the term more specifically refers to the volatile components of magma (mostly water vapor and carbon dioxide) that affect the appearance and explosivity of volcanoes. Volatiles in a magma with a high viscosity, generally felsic with a higher silica (SiO 2) content, tend to produce eruptions that are explosive eruption.
