Wine is usually around 24 proof, or 12 percent alcohol and grain alcohol is 190 proof — pretty darn close to pure alcohol [source: Alcohol.org]. The higher the proof of a given alcohol, the lower the freezing point — in other words, higher alcoholic concentration makes a spirit harder ...

many substances, such as wood, burn in air and burn even more vigourously in pure oxygen). Mixtures do not have fixed precise melting and boiling points (which elements and compounds do have), but instead mixtures melt / freeze and boil / condense over a range of temperatures according to...

Economics does not naturally lend itself to scientifichypothesis testingas does physics. In the field of epistemology, scientists can learn through logical thought experiments, also called deduction, or through empirical observation and testing, also called positivism. Geometry is a logically deductive sci...
This means that we should not think of “applied” chemistry as being inferior to “pure” chemistry, as does the author of one school textbook, who says that, of the two sides of chemistry, “pure” chemistry is “infinitely the more important” (quoted by Hughes 1975, p. 111). Nor ...
(Grown by accident in a glass of salt water that evaporated.) Still, quite white. But, based on your replies, it sounds like an even larger one should be more "glass" like. Come to think of it, the salt in that glass of salty water might not have been exactly pure... Jul 24, ...
The International Union of Pure and Applied Chemistry (IUPAC) definition of adsorption is: "Adsorption vs. Absorption Adsorption is a surface phenomenon in which particles or molecules bind to the top layer of material. Absorption, on the other hand, goes deeper, involving the entire volume of t...
