The University of Bath Macmillan Science 16-19 Project is a family of core and satellite textbooks in biology, chemistry, physics and electronics to cover the common core and option topics in the new A and AS-level syllabuses. All the books have been thoroughly trialled in the classroom and revised accordingly. Through the encouragement of interactive learning, the organization of syllabus content and the emphasis on principles and applications, these books provide an invaluable resource for all 16-19 science courses. The book provides a full account of three important aspects of energy - energy for people, the thermodynamics of energy supplies and the physics of transport. It will therefore be valuable for students taking A-level options in these areas, and as an important reference resource for physics students at A and AS-level. The chapters are grouped in themes to provide ease of access for students following different syllabuses, whilst maintaining a coherent treatment. A range of questions and open-ended exercises of offered to enhance the understanding of these major applications of physics. The book's main features include accessibility to a braod ability range of 16-19 students, promotion of interactive learning through in-text assignments, clear organization of text into main themes, chapters and sections, clear learning objectives and summaries at the start and end of chapters, abundant illustration and photography, and use of institute-recommended abbreviations and symbols and SI units.
