,Energy
The capacity of a system to produce an effect or accomplish work; in
thermodynamics, energy can be stored in a system and transferred across its
boundary.
Conservation of Energy Principle
Energy cannot be created or destroyed; it can only be stored, transferred, or
transformed from one form to another.
First Law of Thermodynamics
The conservation of energy principle applied to thermodynamic systems.
System
The portion of matter or space selected for thermodynamic analysis.
Surroundings
Everything external to the system.
, Boundary
The real or imaginary surface separating the system from its surroundings.
Closed System
A system in which no mass crosses the system boundary, although energy can
cross the boundary as heat or work.
Control Volume
A region of space through which mass can flow; used for open-system analysis.
State
The condition of a system described by its properties at a particular instant.
Process
A change of a system from one state to another.
Thermodynamic Cycle
A series of processes that returns a system to its original state.
Energy Storage
Energy contained within a system; in this chapter, the important macroscopic
forms are internal energy, kinetic energy, and gravitational potential energy.
