Physical Chemistry: Quanta, Matter, and Change second edition takes an exciting and innovative molecular approach to the teaching of physical chemistry. The text focuses on our understanding of the properties of matter at the molecular level, and how these can be linked to the macroscopic world via statistical mechanics and thermodynamics. For the second edition the structure of the text has been radically re-organised. Instead of being in chapters, material is broken down into 97 short 'topics' and related 'topics' are organised into 20 'focus on' sections. 'Roadmaps' at the beginning of each Focus show how topics are interrelated and help students to forge connections between different subjects. This novel approach is designed to improve the digestibility of the text for students and be more flexible for lecturers teaching the subject. The distinguished author team presents the subject in a rigorous but accessible manner, allowing students to gain a thorough understanding of physical chemistry. The text includes numerous learning features, such as self-test questions, notes on good practice, online 'impact on' sections, and example boxes. Furthermore, the mathematics support has been significantly enhanced for this edition, by the inclusion of new 'chemist's toolkits', which link to the more in depth 'Mathematical background' sections. The ground-breaking approach of the second edition of Physical Chemistry: Quanta, Matter, and Change will enable students to gain a deep understanding of this fascinating and important subject area.   New to this edition Radically updated structure to help improve digestibility and flexibility of use, in which material is broken down into short 'topics' which are organised into 'focus on' sections. Significantly enhanced mathematics support for students such as new chemist's toolkit boxes, equation tags, and end of topic equation checklists. New 'roadmaps' at the beginning of each Focus show how topics are interrelated, helping students to develop a fuller understanding of the subject as a whole.
