3 Review(s)

The book aims to impart in-depth knowledge of the subject and highlight the role of chemistry in the field of engineering. The lucid explanation of the topics will help students understand the fundamental concepts and apply them to design engineering materials and solve problems related to them. An attempt has been made to logically correlate the topic with its application. The book deals with basic principles of various branches of chemistry that is physical, inorganic, and analytical and extends the application of concepts to polymer, fuel and material chemistry. Other topics include photochemistry, water and its treatment and corrosion and its control. The chapter for each topic begins with clearly defined learning objectives, followed by introduction of subtopics, their precise and adequate explanation supported with ample illustrations and diagrams. Solved examples are given at the end of relevant subtopics to strengthen the concepts. The chapters conclude with a set of review and practice questions.
