Unit I: ThermoDynamics & ThermoChemistry
The name "thermodynamics" is really a silly name. Think about it; the field deals primarily with the condition of equilibrium, that is, no change or a "static" situation. The actual field that describes non-equilibration properties is "kinetics" or "dynamics," hence the more apt term for this field is really "thermostatics."
Unit III: Acids, Bases & Chemical Equilibria
It is not a revelation to know that matter or chemicals can convert from one species or state of matter to another. Often the general properties that govern this transformation can be described in terms of an equilibrium. That is, a situation whereby the quantity or quality of the sample does not change in time. Such a situation is intimately connected to "thermodynamics" as discussed in Chapter 19. As you will learn in Chem 2C, electrochemistry is the third member of this troika.
Unit II: States of Matter
Macroscopic quantities of matter can exist in only one of three states: Gas, Liquid or Solid. The following are not states of matter: electricity, gels, powders, plasmas, supercritical fluids or your mother's apple pie. Only two aspects determine the state of matter for a specific system/chemical: 1) The (intermolecular) forces within the sample and 2) the conditions outside the sample (e.g. temperature, pressure etc).
