Chapter 2: The First Law Thermodynamics, the study of the transformations of energy. THE BASIC CONCEPTS system, the part of the world in which we have a special interest. surroundings, the region outside the system where we make our measurements. open system, a system with a boundary through which matter can be transferred.

Chapter 2: The First Law closed system, a system with a boundary through which matter cannot be transferred. isolated system, a system with a boundary through which neither matter nor energy can be transferred. 2.1 Work, heat, and energy work, the transfer of energy by motion against an opposing force; d w = – F d z . energy, the capacity to do work. THE BASIC CONCEPTS (cont. .)

Chapter 2: The First Law 2.1 Work, heat, and energy (cont. .) heat, the transfer of energy as a result of a temperature difference. diathermic boundary, a boundary that permits energy transfer as heat. adiabatic boundary, a boundary that does not permit energy transfer as heat. exothermic process, a process that releases energy as heat. endothermic process, a process that absorbs energy as heat. thermal motion, the random motion of molecules.

Chapter 2: The First Law 2.2 The internal energy internal energy, the total energy of a system. state function, a property that depends only on the current state of the system and is independent of how that state has been prepared. First Law of thermodynamics: the internal energy of an isolated system is constant, Δ U = q + w . 2.3 Expansion work expansion work, work of expansion (or compression), d w = – p ex d V .
