About The Book
This Book is designed to cater the need of students of B. Sc. (Pass and Hons.) students of various Indian Universities on the basis of Model curriculum recently proposed by CDC of UGC. The book comprises 569 figures, 266 examples, 233 problems and 336 objective questions. Each problem is followed by its answer.
The inclusion of a Large number of problems and review questions are aimed at evaluating the degree of conceptual comprehension, a Student has acquired as a result of studying the book. The solved examples are targetted to illustrate the theoretical ideals described in the text.
Although, the book is aimed to target B. Sc. students, yet chemists, Material Scientists and Electrical engineers would find it more useful not only in persuing their studies, but also in Professional applications.
The existence of sufficient number of objective questions are framed to help the student immensely to encounter competitive examinations like NET, SLET, ICS and State Civil Services
