THERMODYNAMICS
Basic Concepts
Macroscopic and Microscopic approach

2. Prof. AnandJoshi
WHAT?
Macroscopic and Microscopic approach
Its An Approach To Study Any
Thermodynamics Property.
Our Interest Is In Energy.
&
Other properties are,
Temperature
&
Pressure

3. Prof. AnandJoshi
Macroscopic & Microscopic approach
The Macroscopic Forms Of Energy are those a
system possesses as a whole with respect to some outside
reference frame, such as kinetic and potential energies.
The Microscopic Forms Of Energy are those related to
the molecular structure of a system and the degree of the
molecular activity, and they are independent of outside
reference frames.
Energy
can exist in
numerous
forms such as
Thermal,
Mechanical,
Kinetic,
Potential,
Electric,
Magnetic,
Chemical,
&
Nuclear,
& their sum
constitutes the
Total Energy
(E)of a System
No Absolute Value & Hence Change Is Considered

TEMPERATURE:
Average Kinetic Energy
Of The Molecule
.
It’s A Measure Of The
Heat Of The Body
TEMPERATURE
