Entropy and the Criterion for Equilibrium:
For any given system, it either remains as it is if it is initially at equilibrium or
undergoes a spontaneous irreversible process moving to

Chapter 5 AUXILIARY FUNCTIONS
5.1 Equilibrium State: Need for Additional State Functions
The application of thermodynamics boils down to establishing the criteria of equilibrium
states. However, the condition of the thermodynamic state has to be specified
CHAPTER 1 INTRODUCTION
1.1 Thermodynamics in Materials Engineering
Thermodynamics is a subject that deals with macroscopic
phenomena. It is a phenomenological science where knowledge was
accumulated from observation and the results were condensed into
Chapter 4 Statistical Interpretation of Entropy
A macroscopic state of a gas of N molecules can be characterized by, for example, certain
internal energy at a particular temperature and volume. But microscopically, there may be many
CHAPTER 2 THE FIRST LAW OF THERMODYNAMICS
2.1 History of Heat
J. Becher (1635-1682) and G. E. Stahl (1660-1734) proposed the phlogiston theory. A
substance, the phlogiston, was contained in all combustible bodies. It was liberated on bu
CHAPTER 3 THE SECOND LAW OF THERMODYNAMICS
3.1 Work <-> Heat
Work can be converted into heat within a system, i.e. without any other changes in the
surrounding. Pushing a piston can generate heat in the gas in the container due to compression.
