The hydroxyl group generally makes the alcohol molecule polar. Those groups can form hydrogen bonds to one another and to other compounds. Two opposing solubility trends in alcohols are: the tendency of the polar OH to promote solubility in water, and of the carbon chain to resist it. Thus, methanol, ethanol, and propanol are miscible in water because the hydroxyl group wins out over the short carbon chain. Butanol, with a four-carbon chain, is moderately soluble because of a balance between the two trends. Alcohols of five or more carbons (Pentanol and higher) are effecti ...

Physics (from the Greek, φυσικός (physikos), "natural", and φύσις (physis), "nature") is the science of the natural world dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity.

In solid state physics, the electronic band structure (or simply band structure) of a solid is the series of "forbidden" and "allowed" energy bands that it contains. The band structure determines a material's electronic properties, optical properties, and a variety of other properties. Electronic band structure - Why bands occur. The electrons of a single free-standing atom occupy atomic orbitals, which form a discrete set of energy levels. If several atoms are brought together into a molecule, their ...

Antonyms: psychical (in metaphysics) mathematical (in theoretical physics, e.g., "This choice has no physical consequences, it is purely mathematical" ). The word "physical," when used alone, has several possible meanings in the English language. related to the body. It can specify the quality of an object to occupy space. related to material things; see nature. related to matter and energy, being studied by physics.

In mathematics, the Archimedean property of an ordered algebraic structure, such as a linearly ordered group, and in particular of the real numbers, is the property of having no (non-zero) infinitesimals. Structures that lack infinitesimals are called Archimedean; those that possess infinitesimals are non-Archimedean. For example, see the Archimedean group. A small number x is classed as infinitesimal if the inequality always holds, no matter ho ...

Chemical physics is a subdiscipline of physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics. While at the interface of physics and chemistry, chemical physics is distinct from physical chemistry in that it focuses more on the characteristic elements and theories of physics. Meanwhile, physical chemistry studies the physical nature of chemistry. The distinction between the two fields, nonetheless, is vague, and workers often practi ...

Coherence is a property of waves that measures the ability of the waves to interfere with each other. Coherence physics - Explanation. Two waves that are coherent can be combined to produce an unmoving distribution of constructive and destructive interference (a visible interference pattern) depending on the relative phase of the waves at their meeting point. When combined, waves that are incoherent produce rapidly moving areas of constructive and destructive interference and therefore ...

In physics, a physical body is an object which can be described by the theories of classical mechanics, or quantum mechanics, and experimented upon by physical instruments. This includes the determination of position, and in some cases the orientation in space, as well as means to change these, by exerting forces. For instance, the force of gravity will accelerate a body if it is not supported, thus causing ...

The concept of property or ownership has no single or universally accepted definition. Like other foundational concepts which have great weight in public discourse, popular usage varies broadly. Various scholarly communities (e.g., law, economics, anthropology, sociology) may treat the concept more systematically, but their definitions likewise vary within and between fields. In common use, property is simply 'one's own thing' and refers to the relationship between individuals and the objects which they see as being thei ...

Atomic, molecular, and optical physics is the study of matter-matter and light-matter interactions on the scale of single atoms or structures containing a few atoms. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of the energy scales that are relevant. Physicists sometimes abbreviate the field as AMO physics. All three areas include both classical and quantum treatments. Atomic molecular and optical physics - Atomic physics. ...

Galinstan tends to wet and adhere to many materials, including glass, which limits its use compared to mercury. Galinstan thermometers can be made if the inner tube is first coated with gallium oxide to prevent the alloy from wetting the glass surface. Galinstan is commercially used as a mercury replacement in thermometers due to its nontoxic properties. Galinstan has higher reflectivity and lower density than mercury; it is investigated as a replacement of mercury in spinning mirror telescopes for astronomy. It is also a promi ...

Ambergris is found in lumps of various shapes and sizes, weighing from ½ oz (14 g) to 100 or more pounds (45 or more kg). When initially expelled by the whale or removed from it, the fatty precursor of ambergris is pale white in colour (sometimes streaked with black), soft in consistency, with a disagreeable fecal smell. Following months and years of photo-degradation and oxidation in the ocean, this precursor gradually hardens, developing a dark grey or black colour, a crusty and waxy texture, and a peculiar odour that is at once sweet, ea ...

Cyanuric acid is odorless, hygroscopic, and commonly used as a crystalline powder. On heating, it decomposes at 320-350°C and above emitting toxic fumes which have nitrogen oxides and cyanic acid. The two chemical structures shown at right readily interconvert to each other. Molecular mass: 129.09 g/mole CAS # 108-80-5 The ring in its molecule has aromatic character. Because of this aromatic character, the hydroxyl (-OH) groups in the triol form of the molecule take on a phenolic character, becoming somewhat more acidic than hydroxyls in an alcohol. The hydrogen on any one of the hydro ...

Erythritol - Heat of Solution. Erythritol has a strong cooling effect (negative heat of solution) when it dissolves in water, which combines superbly with mint flavors, but often proves distracting with more subtle flavors and textures. The cooling effect is only present when erythritol is not already dissolved in water, a situation that might be experienced in an erythritol-sweetened frosting, chocolate bar, chewing gum, or hard candy. When combined with solid fats, such as coconut oil, cocoa butter or cow's but ...

A carbonyl group is polar. This makes ketones polar compounds. The carbonyl groups interact with water by hydrogen-bonding. It is a hydrogen-bond acceptor, but not a hydrogen-bond donator, and cannot hydrogen-bond to itself. This makes ketones more volatile than alcohols and carboxylic acids of similar molecular weight. Ketone - Spectroscopic properties. Spectroscopy is an important means for identifying ketones. Ketones and aldehydes will display a significant peak in infrared spectroscopy, at around 1700 wavenumbers (slightly higher or ...

Policosanol is a mixture of a few fatty alcohols derived from the waxes of such plants as sugar cane and yams, as well as beeswax. The most prevalent alcohol in policosanol is octanosol, followed triacontanol. There is a much lower concentration of several other fatty alcohols: behenyl alcohol, lignoceryl alcohol, ceryl alcohol, 1-heptacosanol, 1-nonacosanol, 1-dotriacontanol, and geddyl alcohol. ...
