  2. Dry distillation - Wikipedia

    en.wikipedia.org/wiki/Dry_distillation

    Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  4. Sink - Wikipedia

    en.wikipedia.org/wiki/Sink

    The washstands were small tables on which were placed a pitcher and a deep bowl, following the English tradition. Sometimes the table had a hole where the large bowl rested, which led to the making of dry sinks. From about 1820 to 1900, the dry sink evolved by the addition of a wooden cabinet with a trough built on the top, lined with zinc or ...

  5. Sources and sinks - Wikipedia

    en.wikipedia.org/wiki/Sources_and_sinks

    From left to right: a field with a source, a field with a sink, a field without either. In the physical sciences, engineering and mathematics, sources and sinks is an analogy used to describe properties of vector fields. It generalizes the idea of fluid sources and sinks (like the faucet and drain of a bathtub) across different scientific ...

  6. Cooling bath - Wikipedia

    en.wikipedia.org/wiki/Cooling_bath

    Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.

  8. Dry decontamination - Wikipedia

    en.wikipedia.org/wiki/Dry_decontamination

    Dry decontamination is a method of removing contaminants (such as chemicals, biological particles, or other liquids, gasses, or solids) without the need to use water or other liquids. Decontamination is an essential duty of hazmat responders as it protects victims from harmful reactions to the contaminants.

  9. Dry lab - Wikipedia

    en.wikipedia.org/wiki/Dry_lab

    An example of a dry lab is one where computational or applied mathematical analyses are done on a computer-generated model to simulate a phenomenon in the physical realm. [1] Examples of such phenomena include a molecule changing quantum states, the event horizon of a black hole or anything that otherwise might be impossible or too dangerous to ...
