The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature.
Name Image Region Description Caravane cheese: The brand name of a camel milk cheese produced in Mauritania by Tiviski, [5] a company founded by Nancy Abeiderrhamane in 1987. The milk used to make the cheese is collected from the local animals of a thousand nomadic herdsmen, and is very difficult to produce, but yields a product that is low in lactose.
Furfural is used to make other furan derivatives, such as furoic acid, via oxidation, [30] and furan itself via palladium catalyzed vapor phase decarbonylation. [ 4 ] There is a good market for value added chemicals that can be obtained from furfural.
Melting ice cubes illustrate the process of fusion. Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.
Ingredients: 2 tablespoons extra virgin olive oil. ¼ stick butter. ½ onion, thinly sliced (scallions in season) 2-3 slices prosciutto di Parma, chopped
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
When thawing frozen bread, it's unfortunately common for the loaf to become soggy as it reaches room temperature. Prevent this from happening by placing a paper towel inside the bread bag to ...
