In May 2019, the new SI definitions for amps, kilograms, kelvins and moles came into force. For the mole, the SI unit of the amount of substance, the Avogadro constant was redefined and its value was set as the defining constant. But: How did it come about that a comparative number became a natural constant? Embark on a short journey from the beginnings to the present day: From the gas laws of the 17th century to the new SI system of units of the 21st century. Get to know the meaning of the natural constants in general and the Avogadro constant in particular. Get an overview of the term “mole” and find out which (exemplary) methods can be used to determine the Avogadro constant.

Mathematical modeling of atmospheric composition is a formidable scientific and computational challenge. This comprehensive presentation of the modeling methods used in atmospheric chemistry focuses on both theory and practice, from the fundamental principles behind models, through to their applications in interpreting observations. An encyclopaedic coverage of methods used in atmospheric modeling, including their advantages and disadvantages, makes this a one-stop resource with a large scope. Particular emphasis is given to the mathematical formulation of chemical, radiative, and aerosol processes; advection and turbulent transport; emission and deposition processes; as well as major chapters on model evaluation and inverse modeling. The modeling of atmospheric chemistry is an intrinsically interdisciplinary endeavour, bringing together meteorology, radiative transfer, physical chemistry and biogeochemistry, making the book of value to a broad readership. Introductory chapters and a review of the relevant mathematics make this book instantly accessible to graduate students and researchers in the atmospheric sciences.

The Gaseous State provides a comprehensive discussion on the various areas of concerns in gases. The main concern of the title is the interpretation of the properties of bulk gases in terms of the characteristics of the constituent molecules. The text first details the perfect gas equation, and then proceeds to tackling various gaseous properties. The coverage of the selection includes gas imperfection, collisions, viscosity, thermal conductivity, and diffusion, and energy transfer. The title also covers the Brownian movement and the determination of Avogadro's number. The book will be most useful to undergraduate students of chemistry.

ISBN: 9781947172623

Chemistry 2e is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. The second edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Substantial improvements have been made in the figures, illustrations, and example exercises that support the text narrative. Changes made in Chemistry 2e are described in the preface to help instructors transition to the second edition.

This book provides a comprehensive exposition of the theory of equilibrium thermodynamics and statistical mechanics at a level suitable for well-prepared undergraduate students. The fundamental message of the book is that all results in equilibrium thermodynamics and statistical mechanics follow from a single unprovable axiom — namely, the principle of equal a priori probabilities — combined with elementary probability theory, elementary classical mechanics, and elementary quantum mechanics.
