This book aims at providing information on fundamentals of classical thermodynamics presented in a clear and lucid manner so as the students grasp the same with ease. It will serve as a concise but comprehensive as well as a quality text book for the core course being taught at IITs, NITs and many other universities conducting various UG programs in engineering. The chapter scheme has been kept in a manner so as to use the knowledge
of the preceding chapters in the ensuing one. A good number of solved practical oriented examples have been added along with review questions and unsolved problems at the end of each chapter.
• A concise but comprehensive text book with qualitative approach.
• Emphasis on clarity of fundamentals explained with the help of simple and suitable examples.
• The Laws of thermodynamics and the Availability concept explained by choosing simple illustrations.
• The chapter on Properties of Pure Substance added in the beginning of the text so as to use its knowledge right from the First Law itself.
• Problem solving made easy by way of cautioning the reader regarding complexity during the use of units, explained in the solved examples so as to avoid the common mistakes.
