How the macroscopic world works
ChE210A
Previously, we covered how the world works at a microscopic level-how atoms and molecules interact with each other and what laws govern their time evolution. Now, we take a macroscopic point of view. What happens wh
How the microscopic world works
ChE210A
In order to understand the molecular origins of thermodynamic equilibrium, it is important to first understand the fundamental principles by which molecules interact. Moreover, as science and technology increasingly
Phase equilibrium
ChE210A
It is a familiar fact that pure substances tend to exist in one of three distinct states: solid, liquid, and gas. Heat a crystal up, and at a specific temperature it suddenly melts into a liquid. Continue heating that liquid, and

In the last few lectures, we derived the microscopic probabilities for systems that are at constant temperature, i.e., coupled to an infinitely large energy bath. We will now find the same probabil

What is equilibrium?
ChE210A
At its most basic level, the subject of thermodynamics is the study of the properties of systems and substances at equilibrium. What is meant by equilibrium? A simple way of thinking about equilibrium i
