Über dieses Buch

This book provides the reader with some thermochemistry notes. The intention is to provide a simple, easy to understand text which serves as a complimentary material to more complex books. It also provide students and those beginning in the field with several application examples used in different areas of materials processing. The book presents fully solved problems, some quite often found in major metallurgical operations.



Chapter 1. Laws of Thermodynamics and Auxiliary Functions

Thermodynamics developed from studying the efficiency of early steam engines. Thermodynamics deals with energy exchange or energy transformation in a given system without considering any molecular mechanism. At its core, thermodynamics relates heat and temperature to energy and mechanical work.
Gabriel Plascencia, David Jaramillo

Chapter 2. Phase Equilibria I

In the previous chapter, it was discussed the thermodynamics principles that are the basis of thermochemistry. It was shown how to calculate the energy involved in any chemical or physical transformation. Additionally, it was established the Gibbs free energy as a criterion to know whether or not such transformations would take place under a given set of conditions.
Gabriel Plascencia, David Jaramillo

Chapter 3. Electrochemistry

In chapter one, it was stated that energy can transform into different forms; one of such useful transformations is when electrical energy converts into chemical one or vice versa. Batteries transform the energy released by a chemical reaction into electricity, so we can run different devices like cell phones, computers, personal media players, and even some vehicles.
Gabriel Plascencia, David Jaramillo

Chapter 4. Mixing and Solution Thermodynamics

In nature, we rarely find pure components or elements. We live in a world made of mixtures; therefore, we should shift our attention to mixtures components in solids, liquids, and gases. Because of this, we are more interested in the thermodynamics of mixing.
Gabriel Plascencia, David Jaramillo

Chapter 5. Phase Equilibria II

In the last chapter, interactions between components forming mixtures were discussed. As more constituents were added to the system, the equations describing the thermodynamic quantities become more complex. However, it was shown in the examples section that graphical representation of such equations is very useful in determining those quantities.
Gabriel Plascencia, David Jaramillo

Chapter 6. Exergy

Up to this point, several thermodynamic functions have been developed to predict the equilibrium position of chemical systems, especially those related to metallurgical processes. The examples developed throughout the manuscript represent classical chemical thermodynamics calculations aimed at predicting the behavior of metallurgical systems.
Gabriel Plascencia, David Jaramillo
