During this small ebook an test has been made to set forth the distinguishing gains of the chemical phenomena attribute of outer house. now we have disbursed detailed realization to the theoretical and experimental tools of research of house, fending off although, repetition of the fabric contained in class classes of physics and chemistry. even as, striving to make the e-book as well known as attainable, we restrained ourselves in simple terms to the main crucial details about the nature of the atomic nucleus, the legislation of nuclear energetics, the foundation of assorted types of spectra, and so forth. The scope of the data of physics, chemistry and arithmetic given at our secondary faculties is sort of adequate for figuring out this book.
The textbook is designed for higher grade scholars of secondary faculties. It comprises information regarding the chemical composition of the planets of sun approach, meteorites, the solar, approximately synthesis of components at the stars, the equipment of learning area chemistry, in addition to catalytic nature of nuclear processes.
The writer describes the behaviour of gear at very excessive and intensely low temperatures and pressures, considers the potential for the formation of natural compounds in outer house and in pre-biological interval in the world.

The matter of time in physics and chemistry is heavily regarding the formula of the second one legislation of thermodynamics. hence one other attainable identify of this lecture might have been: "the macroscopic and microscopic facets of the second one legislation of thermodynamics".
''This concise encyclopedia comprises severe details on silicones (i. e. , polysiloxanes) which are commercially to be had for prime functionality functions. even supposing, voluminous literature is on the market to readers, besides the fact that; important details is tough to discover because it continues to be scattered. This booklet has been compiled for a extensive readership and includes rigorously screened chapters on leading edge applied sciences to be had within the box of silicones.

This Imeteorite fell in 1916 in the neighbourhood of Nikolsk~U~suriys~ and was described by O. Baklund in 1916. he magnetic properties of this meteorite were studied fbY N. Akulov and N. Bryukhatov. emainder is iron. ' t ~ Fig. 7. Cross section of iron meteorite "Routon" (the Widmanstatten structure is visible) Fig. 8. Iron meteorite "Boguslavka" that fell on the Earth in 1916 and on falling split apart into two parts rocks of Earth origin, the chemical analysis of meteorites has made it possible to discover in them interesting witnesses of the "life" of these celestial wanderers.

Then, apparently, they slowly (in the course of 108 years) cooled down to 300°C. Fusion probably occurred at a high pressure and then the volatile substances were lost and rapid crystallization took place. Achondrites do not differ much from chondrites in their composition but they do not contain congealed drops, chondrules, Some of the achondrites are very similar to the Earth rock basalt.
It has been proved that amino acids are produced, for example, during electric discharges in mixtures of methane and hydrogen, water, ammonia. Amino acids, apparently, are contained in carbonaceous chondrites - most likely glycine and phenylalanine. The question whether other amino acids are present is not satisfactorily answered as yet. , the amino acids detected were simply impurities introduced by the analyst himself, The same thing happened in the case of chloronaphthalene which was believed to have been brought from outer space, hut which actually got into the substance being tested from the polish used for parquet floors .
