  2. Volatility (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Volatility_(chemistry)

    Volatility can also describe the tendency of a vapor to condense into a liquid or solid; less volatile substances will more readily condense from a vapor than highly volatile ones. [1] Differences in volatility can be observed by comparing how fast substances within a group evaporate (or sublimate in the case of solids) when exposed to the ...

  3. Volatile (astrogeology) - Wikipedia

    The value changes, for example for water in rhyolite n = 0.4111 P and for the carbon dioxide n = 0.0023 P. These simple equations work if there is only one volatile in a magma. However, in reality, the situation is not so simple because there are often multiple volatiles in a magma. It is a complex chemical interaction between different ...

  4. Magmatic water - Wikipedia

    en.wikipedia.org/wiki/Magmatic_water

    Examples of volatiles within magma include water, carbon dioxide, and halogen gases. [1] High pressures allow these volatiles to stay relatively stable within solution. [ 1 ] However, over time, as the magmatic pressure decreases, volatiles will rise out of solution in the gaseous phase, further decreasing the magmatic pressure. [ 1 ]

    These emitted volatiles were measured by GC-MS and the most notable were 2-hexenal and 3-hexenal acetate. It was found that depolarization increased with increasing green leaf volatile concentrations. These results indicate that tomato plants communicate with one another via airborne volatile cues, and when these VOC's are perceived by receptor ...

    Volatile anaesthetics, a class of anaesthetics which evaporate or vaporize 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 cosmetic and flavoring industries

  7. Chemistry: A Volatile History - Wikipedia

    en.wikipedia.org/wiki/Chemistry:_A_Volatile_History

    The periodic table does not however tell us why some elements are highly reactive, others completely inert, why some are volatile, whilst others less so. It wasn't until the beginning of the 20th century that an entirely different branch of science began to unravel the answers to these questions.

    Importance: Topic creator; historian Bill Bryson states, in his A Short History of Nearly Everything, that Gibbs’ Equilibrium paper is "the Principia of thermodynamics". [19] In addition, this paper, in many ways, functions as the mathematical foundation of physical chemistry .

    en.wikipedia.org/wiki/Science_education

    Science education is the teaching and learning of science to school children, college students, or adults within the general public. The field of science education includes work in science content, science process (the scientific method), some social science, and some teaching pedagogy.
