- 2.1: System, Property, State, and Process
- Definition of a system, property, state, and process. A test to determine whether or not a known physical quantity is a property.
- 2.2: The Accounting Concept
- The rate form of the accounting principle, which is valid at any instant in time, and the finite-time form of the accounting principle, which is used to describe a system that has undergone a process over a specified time interval. Includes an example scenario where both forms are used.
- 2.3: Conservation
- Defining the word "conservation" as used in this text. A conserved property cannot be generated or consumed, so all the generation and consumption terms of the accounting principle in a system where this applies will be set to zero.
