Patterned Border Template 3 Purdue University School of Mechanical Engineering Statistical Thermodynamics Concepts of Assemblies and Systems • Assembly: relatively large-scale, macroscopic collection of microscopic constituents (systems). • System: microscopic constituent such as atom or molecule. Microscale or Statistical Thermodynamics • Principal objective: predict and interpret the properties of the assembly. • Properties of systems determined from quantum mechanics. • Properties of assemblies are then determined by applying probability theory to average correctly over the properties of the microscopic systems. Classical thermodynamics • Based upon fundamental laws that are largely empirical in origin (First Law, Second Law) • Fundamental laws used to develop functional relations between thermodynamic properties and work and heat transfer processes. • Intrinsic properties of the constituent, microscopic systems in an assembly are not directly considered.

Patterned Border Template 4 Purdue University School of Mechanical Engineering Introduction to Quantum Mechanics Statistical thermodynamics was an established discipline long before the advent of quantum mechanics in the early 1900's. Classical mechanics was used to determine the properties of the constituent systems (atoms and molecules). The position, energy, and momentum of these classical particles were assumed to be continuously varying quantities. In many cases, for example in describing the translational energy of atoms and molecules, classical mechanics is reasonably accurate.
