Levine, Physical Chemistry, Sections 1.2, 2.1{2.4 Key Concepts Thermodynamic variables can be categorized based on how they change when the system size is changed. Intensive quantities, such as pressure and temperature, are independent of system size. Extensive variables, such as volume, mass, surface area, depend on the size of the system. Thermodynamic variables exist in conjugate pairs. The product of the units of these pairs is always energy. They always consist of one intensive variable (a force), for example pressure (P), and one extensive variable (displacement), like volume (V). They appear paired in work terms like PdV; dA, etc. Thermodynamic systems can be described by determining what can pass through the bo...
