Book Description
Familiar combinations of ingredients and processing make the structures that give food its properties. For example in ice cream, the emulsifiers and proteins stabilize partly crystalline milk fat as an emulsion, freezing (crystallization) of some of the water gives the product its hardness and polysaccharide stabilizers keep it smooth. Why different recipes work as they do is largely governed by the rules of physical chemistry. This textbook introduces the physical chemistry essential to understanding the behavior of foods. Starting with the simplest model of molecules attracting and repelling one another while being moved by the randomizing effect of heat, the laws of thermodynamics are used to derive important properties of foods such as flavor binding and water activity. Most foods contain multiple phases and the same molecular model is used to understand phase diagrams, phase separation and the properties of surfaces. The remaining chapters focus on the formation and properties of specific structures in foods – crystals, polymers, dispersions and gels. Only a basic understanding of food science is needed, and no mathematics or chemistry beyond the introductory college courses is required. At all stages, examples from the primary literature are used to illustrate the text and to highlight the practical applications of physical chemistry in food science.

Book Description
This textbook presents a straightforward introduction to physical chemistry. Whilst stressing the fundamentals of the subject, it avoids the mathematical details of specialised techniques such as quantum theory, nuclear magnetic resonance, and spectroscopy. In order to promote an appreciation of 3-dimensional structure in the study of stereo-chemistry and solids, many of the illustrations are presented as stereoscopic views, and directions for observing them are given in an appendix. Each chapter ends with a set of problems of varying degrees of difficulty, which will assist the student in gaining familiarity with the themes of the book, and in testing their ability to apply these themes to new situations; full solutions are provided. The S1 system of units is used throughout and appendices serve as a useful reference source of numerical data. Some mathematical arguments are also developed in appendices, because their inclusion in the text might distract readers from the development of the subject. The book has been developed front an earlier publication by the authors entitled Modern Physical Chemistry, published by Penguin Books Ltd.

Book Description
Designed for a two-semester introductory course sequence in physical chemistry, Physical Chemistry: A Modern Introduction, Second Edition offers a streamlined introduction to the subject. Focusing on core concepts, the text stresses fundamental issues and includes basic examples rather than the myriad of applications often presented in other, more encyclopedic books. Physical chemistry need not appear as a large assortment of different, disconnected, and sometimes intimidating topics. Instead, students should see that physical chemistry provides a coherent framework for chemical knowledge, from the molecular to the macroscopic level. The book offers: Novel organization to foster student understanding, giving students the strongest sophistication in the least amount of time and preparing them to tackle more challenging topics Strong problem-solving emphasis, with numerous end-of-chapter practice exercises, over two dozen in-text worked examples, and a number of clearly identified spreadsheet exercises A quick review in calculus, via an appendix providing the necessary mathematical background for the study of physical chemistry Powerful streamlined development of group theory and advanced topics in quantum mechanics, via appendices covering molecular symmetry and special quantum mechanical approaches

Book Description
This book introduces both physical and biological scientists to important thermodynamic and kinetic interpretations of living systems that involve major conceptual developments in the application of physio-chemical ideas. A concluding discussion relates these developments to other widely discussed ideas that have been recently applied to living systems, including thermodynamic aspects of evolution, information theory, and hierarchy and the question of reductionism. Students and researchers in both physical and biological science will find this mathematically simplified account to be a clear and accessible introduction to the physical chemistry of biological organization.

Book Description
The third edition of this text has been completely rewritten and revised. It is intended for first- and second-year undergraduates in chemistry taking physical chemistry courses, and for undergraduates in other science and engineering subjects that require an understanding of chemistry. The author gives more attention to the solid and liquid states than is found in other texts on this subject, and introduces topics such as computer simulation and quasicrystals. Each chapter concludes with a set of problems, to which there are solution notes, designed to lead the reader to familiarity with the subject and its application in new situations. Computer programs designed to assist the reader are downloadable from the World Wide Web, from the time of publication. Detailed solutions to the problems will also be available via the World Wide Web. See http://www.cup.cam.ac.uk/stm/laddsolutions.htm. This modern text on physical chemistry will be of interest to undergraduate students in chemistry and also students in other areas of science and engineering requiring a familiarity with the subject.

Book Description
Most people remember chemistry from their schooldays as largely incomprehensible, a subject that was fact-rich but understanding-poor, smelly, and so far removed from the real world of events and pleasures that there seemed little point, except for the most introverted, in coming to terms with its grubby concepts, spells, recipes, and rules. Peter Atkins wants to change all that. In this Very Short Introduction to Chemistry, he encourages us to look at chemistry anew, through a chemist's eyes, in order to understand its central concepts and to see how it contributes not only towards our material comfort, but also to human culture. Atkins shows how chemistry provides the infrastructure of our world, through the chemical industry, the fuels of heating, power generation, and transport, as well as the fabrics of our clothing and furnishings. By considering the remarkable achievements that chemistry has made, and examining its place between both physics and biology, Atkins presents a fascinating, clear, and rigorous exploration of the world of chemistry - its structure, core concepts, and exciting contributions to new cutting-edge technologies. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
