It has a density of 6.11 gm/cc. What is the melting point and boiling point of an element? The boiling point is the temperature at which a material changes from a liquid to a gas (boils) while the melting point is the temperature at which a material changes from a solid to a liquid (melts). Keep in mind that a material's melting point is the same as its freezing point. Since it is difficult to measure extreme temperatures precisely without bias, both have been cited in the literature as having the higher boiling point. Boiling Natural vanadium is a mostly a mixture of the two isotopes, vanadium-50 (0.24%) and vanadium-51 (99.76%). Properties: Vanadium has a melting point of 1890+/-10C, boiling point of 3380C, specific gravity of 6.11 (18.7C), with a valence of 2, 3, 4, or 5. Pure vanadium is a soft, ductile bright white metal. When considered as the temperature of the reverse change from liquid to solid, it is called the freezing point or crystallization point. Unlike gases or liquids, solid materials tend to keep their shape when undergoing thermal expansion. This WISER content is available in multiple languages.

The mean free path also depends on the diameter of the molecule, with larger molecules more likely to experience collisions than small molecules, which is the average distance traveled by an energy carrier (a molecule) before experiencing a collision. Vanadium compounds (pentoxide and certain vanadates) are used as catalysts in the contact process for manufacturing sulfuric acid; as oxidation catalysts in the syntheses of phthalic and maleic anhydrides; in the manufacture of polyamides such as nylon; and in the oxidation of such organic substances as ethanol to acetaldehyde, sugar to oxalic acid, and anthracene to anthraquinone. vanadium (V), chemical element, silvery white soft metal of Group 5 (Vb) of the periodic table.

Vanadium Melting Point and Boiling Point. Alinear expansion coefficientis usually employed in describing the expansion of a solid, while a volume expansion coefficient is more useful for a liquid or a gas. The element was rediscovered (1830) by the Swedish chemist Nils Gabriel Sefstrm, who named it after Vanadis, the Scandinavian goddess of beauty and youth, a name suggested by the beautiful colours of vanadiums compounds in solution. Vanadium The first theory explaining mechanism of melting in the bulk was proposed by Lindemann, who used vibration of atoms in the crystal to explain the melting transition. At some point the amplitude of vibration becomes so large that the atoms start to invade the space of their nearest neighbors and disturb them and the melting process initiates. Maleic anhydride is produced by the V2O5-catalysed oxidation of butane with air: Maleic anhydride is used for the production of polyester resins and alkyd resins.[15].
