THERMODYNAMICS: AN ENGINEERING APPROACH (SI Edition) by CENGEL aims to provide a comprehensive introduction to the subject of thermodynamics, which deals with energy and its transformations. This book is suitable for two sequential courses in thermodynamics and assumes students have an adequate background in calculus and physics. The text emphasizes fundamental principles while also illustrating how computational tools are applied in engineering practice. Using the traditional classical or macroscopic approach as the primary framework, it supports this with appropriate microscopic arguments, aligning well with students’ intuitive understanding and facilitating easier learning of thermodynamics concepts.
