Thermodynamic System
System—A quantity of matter or a region in space bounded by an arbitrary surfaces for study.
Surrounding—The mass or region outside the system.
Boundary—The surfaces separate the system from its surroundings.
The boundary can be real or imaginary, fixed or variable.
–It is critically important to define your system before attempting to solve a thermodynamic problem.

A thermodynamic system is a precisely specified macroscopic region of the universe, defined by boundaries or walls of particular natures, together with the physical surroundings of that region,macroscopic THERMODYNAMIC SYSTEM A thermodynamic system has a characteristic set of thermodynamic parameters, or state variables. They are experimentally measurable macroscopic properties, such as volume, pressure, temperature, electric field, and othersthermodynamic parameters The set of values of the thermodynamic parameters necessary to uniquely define a state of a system is called the thermodynamic state of a system.thermodynamic state

Control VolumeA control volume is a fixed region in space chosen for the thermodynamic study of mass andenergy balances for flowing systems. The boundary of the control volume may be a real orimaginary envelope. The control surface is the boundary of the control volume.
