Thermodynamics Notes
1. Thermodynamic System
Definition: A system is a part of the universe selected for study.
Surroundings: Everything outside the system.
Boundary: Surface separating system and surroundings.
2. Types of System
- Open System: Exchange of mass and energy.
- Closed System: Exchange of energy only.
- Isolated System: No exchange of mass or energy.
3. Thermodynamic Parameters
Intensive Properties
- Independent of mass (Temperature, Pressure)
Extensive Properties
- Depend on mass (Volume, Energy)
4. Thermodynamic Process
- Isothermal: T = constant
- Adiabatic: Q = 0
- Isobaric: P = constant
- Isochoric: V = constant
5. Thermodynamic State
- Initial State: Before process
- Final State: After process
- Equilibrium State: No change with time
Quick Difference
State: Condition of system (P, V, T)
Process: Path between states
