What is Thermodynamics?
Thermodynamics: The science of
energy.
 Energy: The ability to cause changes.
 The name thermodynamics stems from
the Greek words therme (heat) and
dynamis (power).


The first law of thermodynamics:



Energy cannot be created or destroyed.
An expression of the conservation of energy
principle.
Conservation of energy principle:

14
Energy can change from one form to another
but the total amount of energy remains
constant.

What is Thermodynamics? cont.
The second law of thermodynamics:
It asserts that energy has quality as well
as quantity, and actual processes occur
in the direction of decreasing quality of
energy.
 Classical thermodynamics: A
macroscopic approach to the study of
thermodynamics that does not require a
knowledge of the behavior of individual
particles.
 Statistical thermodynamics: A
microscopic approach, based on the
average behavior of large groups of
individual particles.

Application Areas of Thermodynamics
All activities in nature involve some interaction between energy and matter; thus, it is
hard to imagine an area that does not relate to thermodynamics in some manner.

Thermodynamic Systems
 System: A quantity of matter
or a region in space chosen
for study.
 Surroundings: The mass or
region outside the system
 Boundary: The real or
imaginary surface that
separates the system from
its surroundings.

19
The boundary of a system can
be fixed or movable.

Thermodynamic Systems
 Systems may be considered to
be closed or open.

Closed system (Control mass): A
fixed amount of mass, and no mass
can cross its boundary

Open system (Control volume): A
fixed amount of volume, where mass
can cross its boundary
 Examples of Closed Systems:

Thermodynamic Systems
Open system (control volume): A fixed amount of volume, where
mass can cross its boundary.
 It usually encloses a device that involves mass flow such as a
compressor, turbine, nozzle.
 Control surface: The boundaries of a control volume. It can be real
or imaginary.

A control volume
can involve
fixed, moving,
real, and
imaginary
boundaries.
