  2. Precipitation (chemistry) - Wikipedia

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

    In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [ 1 ] [ 2 ] The solid formed is called the precipitate . [ 3 ] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant .

  3. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq). The word aqueous (which comes from aqua) means pertaining to, related to, similar to, or dissolved in, water. [1] [2] As water is an excellent solvent and is also naturally abundant, it is a ubiquitous solvent ...

  4. Precipitation types - Wikipedia

    en.wikipedia.org/wiki/Precipitation_types

    Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.

    Thus, fog and mist are not precipitation; their water vapor does not condense sufficiently to precipitate, so fog and mist do not fall. (Such a non-precipitating combination is a colloid .) Two processes, possibly acting together, can lead to air becoming saturated with water vapor: cooling the air or adding water vapor to the air.

  6. Rain and snow mixed - Wikipedia

    en.wikipedia.org/wiki/Rain_and_snow_mixed

    Rain and snow mixed (American English) or sleet (Commonwealth English) is precipitation composed of a mixture of rain and partially melted snow.Unlike ice pellets, which are hard, and freezing rain, which is fluid until striking an object where it fully freezes, this precipitation is soft and translucent, but it contains some traces of ice crystals from partially fused snowflakes, also called ...

  7. Precipitation hardening - Wikipedia

    en.wikipedia.org/wiki/Precipitation_hardening

    Like modulus hardening, the analysis of interfacial area can be complicated by dislocation line distortion. Order strengthening occurs when the precipitate is an ordered structure such that bond energy before and after shearing is different. For example, in an ordered cubic crystal with composition AB, the bond energy of A-A and B-B after ...

    What does a 30% chance of rain actually mean? Don't overthink it, meteorologists say. The question was sparked by a viral video that has received millions of views, originating on TikTok by user ...

  9. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    The term precipitation is normally reserved for describing a phase change from a colloid dispersion to a solid (precipitate) when it is subjected to a perturbation. [19] Aggregation causes sedimentation or creaming, therefore the colloid is unstable: if either of these processes occur the colloid will no longer be a suspension.
