- 1.1: Thermodynamic Systems
- A thermodynamic system—or just simply a system—is a portion of space with defined boundaries that separate it from its surroundings (see also the title picture of this book). The surroundings may include other thermodynamic systems or physical systems that are not thermodynamic systems.
- 1.2: Thermodynamic Variables
- The system is defined and studied using parameters that are called variables. These variables are quantities that we can measure, such as pressure and temperature.
