ABSTRACT: It is customary to use the canonical ensemble to represent a s ystem that is in equilibrium with a thermal reservoir. Although familiar ma croscopic relations between internal energy, entropy, free energy, heat and work are easily derived from the canonical ensemble, this ensemble does no t accurately describe a nanoscale system that is strongly coupled to its su rroundings, such as a biomolecule in aqueous solution. I will discuss a mod ified thermodynamic framework that describes a classical system of arbitrar y size that is strongly coupled to its thermal environment.  Within th is framework, key thermodynamic quantities are defined microscopically and are shown to obey thermodynamic relations including both the first and seco nd law, as well as nonequilibrium fluctuation theorems. These quantities sc ale up to their macroscopic values when the system of interest is large. Th us a unifying framework is developed, which encompasses nanoscale, stochast ic thermodynamics at one end, and traditional macroscopic thermodynamics at the other. A central element in this approach is a thermodynamic definitio n of the volume of the system of interest, which converges to the usual geo metric definition when the system is large.
