In chemistry, materials science, and physics, the liquidus is a line on a phase diagram above which a given substance is stable in the liquid phase. Most commonly, this line represents a transition temperature. The liquidus may be a straight line, or it may be curved, depending upon the substance. The liquidus is most often applied to binary systems such as solid solutions, including metal alloys. Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). ... The Materials Science Tetrahedron Materials science is a multidisciplinary field focusing on functional solids, whether the function served is structural, electronic, thermal, chemical, magnetic, optical, or some combination of these. ... Wikibooks Wikiversity has more about this subject: School of Physics sci. ... A phase diagram or phase space is a useful construct used in mathematics and physics to demonstrate and visualise the changes in a given system. ... HI LIQUIDX ^_^ Your name is now immortalised within the realms of Wikipedia! A liquid will assume the shape of its container. ... Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ... Binary system may refer to one of the following. ... In chemistry, a metal (Greek: Metallon) is an element that readily forms ions (cations) and has metallic bonds, and it is sometimes said that it is similar to a cation in a cloud of electrons. ... An alloy is a combination, either in solution or compound, of two or more elements, at least one of which is a metal, and where the resultant material has metallic properties. ...

The liquidus may be contrasted to the solidus. The liquidus and solidus do not necessarily align or overlap; if a gap exists between the liquidus and solidus, then within that gap, the substance is not stable as either a liquid or a solid. Solidus can refer to: slash, a punctuation symbol solidus, a coin used in Ancient Rome a transition temperature in metal alloys Solidus Snake, a character in Metal Gear Solid 2 This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. ... A solid is a state of matter, characterized by a definite volume and a definite shape (i. ...
