After the course, the student is able to:
- Explain/describe phenomena of flow, heat and fluid properties from the principles of thermodynamics.
- Describe the thermodynamic behavior of multicomponent fluids in the appropriate mathematical structures.
- Explain / describe models of gases and liquids, co-existing phase systems, chemical reactions.
- Describe and analyse the behavior of chemical reaction mechanisms.
- Apply the knowledge to flow systems with heat exchange, chemical reactions and/or phase transitions.
- Have knowledge on statistical thermodynamics to deepen the understanding of thermodynamic relations.
- Have knowledge on statistical thermodynamics to understand how the thermodynamic properties of a system derive from the atomistic composition of the system.

The course starts with a recapitulation of the three laws of thermodynamics, with an emphasis on the concept of entropy. Subsequently the thermodynamic potentials, like enthalpy and the Helmholtz and Gibbs free energies, are introduced through Legendre transformation. The relations between potentials, their differentials and curvature are described by means of the equations of Euler and Gibbs-Duhem. The acquired knowledge is applied to the combination of heat and mass flow. It is demonstrated that the fundamental quantities sought in the laboratory are those which are required for determining the potentials. A thorough discussion will be provided on models for fluids and gases and their equations of state. Subsequently the course will have a smooth transition to statistical mechanics and its relevance to thermodynamics. As the thermodynamic properties of a system ultimately result from the atomic composition of the system, the fundamental relations coupling the macro level to the micro level are discussed and applied to derive thermodynamic potentials and equations of state for crystals, ideal gasses and non-ideal gasses. Finally chemical reaction rates and equilibrium of heterogeneous systems will be presented. The course will provide a thorough background for students who will be studying fluid mechanics, chemical reactor systems or multiphase systems, either experimentally or theoretically.
