System
whatever we want to study. It may be as simple as a free body or
as complex as an entire chemical refinery.
Surrounding
everything external to the system
Boundary
the system is separate from its surrounding from its surrounding by a boundary that may or may not be in motion
Control system/ Control mass
a fixed quantity of mass
control volume
a region of space through which mass may flow.

control mass + control volume =
control surface
Closed System
when a particular quantity of matter is under study.
Isolated System
A special type of closed system that does not interact in any way
with its surroundings
the choice of system boundary is governed by two considerations:
(1) what is known about a possible system, particularly at its boundaries, and (2) the
objective of the analysis.
Classical Thermodynamics
The macroscopic approach to thermodynamics is concerned with the gross or overall behavior.
