This presentation defines a thermodynamic system as a quantity of matter that is the focus of analysis to study changes in properties from the exchange of heat and work with surroundings. Thermodynamic systems can be open, closed, or isolated. An open system allows for mass and energy transfer with surroundings, like engines. A closed system keeps mass constant while allowing energy transfer, like a pressure cooker. An isolated system exchanges neither mass nor energy, like a thermos flask or the universe.

3. Thermodynamic System:-
• A definite quantity of matter on which we
focus our attention for its thermodynamic
analysis i.e., to study the change in properties
due to exchange of energy in the form of heat
annd work is called thermodynamic system
• The system may be a quantity of steam, a
mixture of gas and vapour or a piston cylinder
assembly of an internal combustion engine.

4. • System:-Anything which are kept in
consideration is called -
System.
• Surrounding:-Everything external to the system
is known as Surrounding.
• Boundary:-The thermodynamic system and
surroundings are separated by an envelope
called Boundary of a system.
• Universe:-Thermodynamic
system+surrounding=Universe

5. Classification of
Thermodynamic system
• Open system:-in open system, the mass as
well as energy transfer may take place
between system and its surroundings.
• Most of Engineering devices are open system.

6. Example of open system:-
• Internal combustion engines
• Air compressor
• Water pump
• Steam engine
• Boiler
• Tutbine

7. Closed system:-
*In closed system, the mass with in the
boundary of the system remains constant
and only the energy transfer may take place
between the system and its surroundings.
Examples of closed system
1.Pressure cooker
2.A rubber balloon filled with air and tightly
closed
3.The gas confined between a piston and
cylinder

8. Isolated system:-
*In an isolated system,neither mass nor
energy transfer takes place between the
system and its surroundings.
Examples of isolated system
1.Thermos flask
2.The universe
