Study Notes
Types of Systems
- A closed system does not exchange matter or energy with its surroundings.
- A semi-open system (or open system) can exchange matter but not energy with its surroundings.
- An isolated system does not exchange either matter or energy with its surroundings.
Thermodynamic Equilibrium
- Thermodynamic equilibrium is characterized by a state of balance, where there are no changes in the system's properties over time.
System Interactions
- An open system can interact with its surroundings by exchanging both matter and energy.
System Description
- The physical condition of a thermodynamic system at a given time is described as its state.
