# What Parts of Thermodynamics Are in Thermo-CD?

## Topics in Modern Thermodynamics include:

### Classical Thermodynamics

Characterize the behavior of large groups of molecules based on properties of the entire group of molecules, such as temperature and pressure.

### Statistical Thermodynamics

Characterize the behavior of groups of molecules based on the properties of each individual molecule and the ways in which molecules interact.

### Phase Equilibrium Thermodynamics

Characterize the behavior of multiple phases that exist in equilibrium with each other.

### Chemical Reaction Equilibrium Thermodynamics

Characterize the behavior of systems in which the reactants and products of one or more reversible chemical reactions are at equilibrium.

### Solution Thermodynamics

Characterize the behavior of systems that contain more than one chemical species in a mixture.

### Pure Component Thermodynamics

Characterize the behavior of systems that contain a pure component.

### Ch 1, Lesson A, Page 2 - What Parts of Thermodynamics Are in Thermo-CD?

• The study of thermodynamics is so broad that it helps to divide in several different ways.
• Classical Thermodynamics takes a macroscopic approach to the behavior of matter.
We measure properties such as temperature and pressure to help us predict other properties and to
predict the behavior of matter as it undergoes a process.
• In contrast, Statistical Thermodynamics strives to predict the behavior of macroscopic masses of matter based on the properties of the individual molecules that make up the mass.
• In this course, we will study Classical Thermodynamics.
• The study of thermodynamics can also be divided into Pure Component and Solution Thermodynamics.
• Solution Thermodynamics is a bit more complicated than Pure Component Thermodynamics.
• The good news for you is that, in this program, we will only study Pure Component Thermodynamics.
• Another major area of Thermodynamics is the study phase equilibrium.  We will study this in some detail in chapter 2 and it will be an important part of almost every other chapter.
• Another important area of thermodynamics is the study of chemical reaction equilibrium.
