Enriches fundamental knowledge of the students about dynamism of the process from thermodynamic and kinetic considerations

1. The students will understand equilibrium properties of macroscopic systems, laws of thermodynamics, and fundamental thermodynamics variables.
2. The students will understand the concept of free energy, chemical potential, and chemical equilibrium.
3. The students will be capable of linking between the free energy composition curves and phase diagrams which forms the basis of materials engineering .
4. The students will be capable of utilizing concept of the thermodynamics in solving some of the metallurgical problems.
5. The students will understand the concept of rates of chemical reactions.
6. The students will be aware of the kinetic limitations to achieve equilibrium conditions in the perspective of metallurgical phenomena.
