This textbook offers a clear, progressive introduction to thermodynamics, tailored for university students and future engineers eager to understand the physical principles behind engines and refrigeration systems. It begins from the basics and progressively covers all the important concepts:

1 Fundamental Concepts

Review the essential concepts for the study of thermodynamics

Concept of energy; First law; Mech. energy; Work; Heat; Temperature.

2 Closed Systems

Quantify energy transfers in a fixed quantity of fluid

Quantification of work and heat in a closed system; Concept of irreversibility.

3 Open Systems

Quantify energy transfers in a continuously-flowing fluid

Usefulness of open and closed systems; Quantification of work and heat.

4 The Ideal Gas

Predict air temperature and quantify its forms of energy

Advantages and limits of the ideal gas model; Basic elementary processes.

5 Liquids and Vapors

Predict water temperature and quantify its forms of energy

Phase changes, property calculations…
