Proudly serving the scientific community for over a century, this 97th edition of the CRC Handbook of Chemistry and Physics is an update of a classic reference, mirroring the growth and direction of science. This venerable work continues to be the most accessed and respected scientific reference in the world. An authoritative resource consisting of tables of data and current international recommendations on nomenclature, symbols, and units, its usefulness spans not only the physical sciences but also related areas of biology, geology, and environmental science.The 97th edition of the Handbook includes 20 new or updated tables along with other updates and expansions. It is now also available as an eBook. This reference puts physical property data and mathematical formulas used in labs and classrooms every day within easy reach.New Tables:Surface Active Chemicals - Table of Properties of the Most Important Surfactants (Solubility, Physical Constants, Critical Micelle Concentration, Hydrophilic-Lipophilic Balance, etc.)Nanomaterial Safety Guidelines - Definition of Terms in Nanoscience; Guidelines for Safe Handling and Disposal Updated and Expanded Tables:CODATA Values of the Fundamental Physical Constants - 2014 valuesStandard Atomic Weights - 2015 Changes Made by IUPACAtomic Masses and Abundances - Update of AbundancesSurface Tension of Common Liquids - Addition of New Compounds and UpdatesBasic Instrumental Techniques of Analytical Chemistry - Expansion to Cover Colorimetry and RefractometryBond Dissociation Energies - Addition of Recently Published DataPhoton Attenuation Coefficients - Addition of Absorption Edge DataClassification of Electromagnetic Radiation - Update with Modern TerminologyAstronomical Constants - Update with New Recommended ConstantsSolar System Properties - Updates with Newly Discovered Satellites Interstellar Molecules - Update with Complete List of Molecules Observed to DateMajor World Earthquakes - Update through 2015Atmospheric Concentration of CO2 - Update through 2015Global Temperature Trend - Update through 2015Abbreviations Used in the Assessment and Presentation of Laboratory Hazards - Update and ExpansionRelative Dose Ranges for Ionizing Radiation - ExpansionThreshold Limits for Airborne Contaminants - Update to 2015 RecommendationsChemical Carcinogens - Update to 2015 Recommendations of National Toxicology Program
