Thermodynamics overview [tln2]
and open systems
The study of equilibrium thermodynamics cannot do without processes that
connect equilibrium states. Processes necessarily disturb the equilibrium.
During a generic process between equilibrium states some
Classication of thermodynamic systems
Criterion: Thermodynamic contact.
1. Mechanical interaction (with work source).
Exchange of energy via work performance.
2. Thermal interaction (with heat reservoir).
Exchange of energy via heat transfer.
Equations of state
The empirical specication of a thermodynamic system is traditionally expressed in the form of two kinds of equations of state.
Thermodynamic equation of state:
Functional relation between thermodynamic variables.
For example: p
