Thermodynamics: Systems, Cycles, and Applications
Thermodynamic Systems
Types of Systems
Closed System: Exchanges energy but not mass with its surroundings.
Open System: Exchanges both energy and mass with its surroundings.
Isolated System: Exchanges neither energy nor mass with its surroundings.
Thermodynamic Properties
Properties define the state of a system and can be:
- Intensive: Independent of mass (e.g., pressure, density).
- Extensive: Dependent on mass (e.g., volume, energy).
- Specific Properties: Extensive properties per unit mass.
