A vapor can exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid). A supercritical fluid (SCF) is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively. In this state, the distinction between liquid and gas disappears.
The solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature specifies the temperature below which a material is completely solid, [2] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium.
An ore deposit is an economically significant accumulation of minerals within a host rock. [9] This is distinct from a mineral resource in that it is a mineral deposit occurring in high enough concentration to be economically viable. [4] An ore deposit is one occurrence of a particular ore type. [10]
Bitumen – highly viscous liquid or semi-solid form of petroleum. Blende; Brimstone – sulfur; Flowers of sulfur – formed by distilling sulfur. Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash. Caustic Soda/caustic marine alkali – sodium hydroxide, NaOH, formed by adding lime to natron.
The video starts with the racoon eyeing two mounds of Jello on a plate. It's curious, and sniffs and grabs it with one hand. It's not sure if it should eat or play with it!
Chromite and magnetite are ore minerals that form in this way. [1] Liquid immiscibility: sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma. Two liquids that will not mix are called immiscible; oil and water are an example.
In materials science, liquefaction [1] is a process that generates a liquid from a solid or a gas [2] or that generates a non-liquid phase which behaves in accordance with fluid dynamics. [3] It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to ...
Mesophases between solid and liquid. Georges Friedel (1922) called attention to the "mesomorphic states of matter" [3] in his scientific assessment of observations of the so-called liquid crystals. Conventionally a crystal is solid, and crystallization converts liquid to solid. The oxymoron of the liquid crystal is resolved through the notion ...
