Classical Mechanics


Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, such as spacecraft, planets, stars, and galaxies. Within these domains, it produces very accurate results. And thus, is one of the oldest and largest subjects in science, engineering and technology.

Thermodynamics of Enzyme-Catalyzed Reactions

By: Robert N. Goldberg

Technical Reference Publication

Introduction: Aqueous sulfuric acid is an economically important chemical when judged by most standards of evaluation. It is by far the largest volume chemical commodity in the world. Its major uses include fertilizer production, petroleum refining, extraction of metals from their ores, production of inorganic pigments, pickling of iron and steel, synthesis of surface active agents, and as a reactant in the lead-acid storage battery (Donovan and Salamone). Sulfuric acid ...

Thermodynamic Properties of Alkali Metal Hydroxides. Part 1. Lithi...

By: L.V. Gurvich

Technical Reference Publication

Introduction: The thermodynamic properties of condensed and gaseous lithium, sodium, potassium, rubidium, and cesium hydroxides in standard states have been reevaluated. This activity was stimulated by the existence of new data since the time of publication of four critical reviews containing analogous information.

By: Reiner Tillner-Roth

Technical Reference Publication

Introduction: The mixture (water + ammonia) is an important working fluid in absorption-refrigeration cycles. Recently, this mixture has also been considered as a working fluid in future power generation plants based on the Kalina cycle. For design and simulation of such machinery, an accurate description of the thermodynamic properties of the mixture (water + ammonia) for a wide range of pressure, temperature, and composition is needed.

Behavior of the Ab-Type Compounds

By: Leo Merrill

Technical Reference Publication

Introduction: This is the second in a series of papers on the subject of the behavior of materials at high pressure. In a previous paper 1411, data on polymorphic phase changes and melting curves have been compiled and evaluated for the elements. This review is a continuation of that effort, and deals with the AB-type compounds. The types of data included are mainly the thermodynamic parameters of the solid-solid phase boundaries and melting curves. In most of the studie...

Rate Constants for Reactions of Inorganic Radicals in Aqueous Solution

By: Pedatsur Neta

Technical Reference Publication

Introduction: Since the publication of the original compilation on this topic in 1979' the number of measured rate constants for reactions of inorganic radicals has more than doubled. Because of the importance of these radicals as basic chemical species, in the study of electron transfer theory, as well as in atmospheric and industrial processes, it is necessary to update the compilation. The present tables include the rate constants presented in the original compilation...

Experimental Stark Widths and Shifts for Spectral Lines

By: N. Konjevic

Technical Reference Publication

Introduction: With this tabulation we continue the series of critical reviews and tables on experimental Stark broadening data for spectral lines of non-hydrogenic atoms and ions which we started in 19761 and updated in 1984. In this new installment, we cover the period from 1983 to the end of 1988, and we have now merged the data on atoms and ions into a single set of tables. But in all other respects we have adhered to the format of our previous reviews, and we have su...

Spectral Data and Grotrian Diagrams for Highly Ionized

By: Toshizo Shirai

Technical Reference Publication

Introduction: We have undertaken to publish a series of compilations of spectra of highly ionized atoms of particular interest to the fusion energy community. These selected elements occur as impurities in wall materials of fusion machines or are internally injected into the hot plasmas for diagnostics. Much new work on these spectra has appeared in recent years. We have critically compiled these data into single publications for each element; each publication includes w...

By: Eugene S. Domelski

Technical Reference Publication

Introduction: As part of a continuing program of collecting and evaluating data on the thermodynamic properties of organic compounds, selected values are reported here for the heats of combustion and heats of formation of 719 organic compounds containing the elements carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur (CHNOPS). Certain classes of compounds, such as amino acids, carbohydrates, glyceryl esters, and peptides, have been covered exhaustively because of...

High Temperature Properties and Decomposition of Inorganic Salts

By: Kurt H. Stem

Technical Reference Publication

Introduction: Volumetric characteristics (such as solution density, apparent molal volumes. ionic apparent volumes, etc.) of multiple-solute electrolyte solutions in a wide range of solute concentrations and solution temperatures are of fundamental importance for the understanding of numerous physicochemical processes occurring in various branches of the chemical industry as well as in the natural environment. The most important application of the volumetric solution pro...

The Observed Properties of Liquid Helium at the Saturated Vapor Pr...

By: Russell J. Connelly

Technical Reference Publication

Introduction: Liquid helium has been studied intensively for more than three quarters of a century: indeed one may advance the claim that it is the most studied pure substance in the history of science. Our group, pursuing certain theoretical topics in the 1960's became aware of the unwelcome impact of faulty data in testing ideas on the theory of super fluidity. We therefore began a collection of well-documented data which first appeared in the book by a further set of ...
