Course content

The course shall give knowledge in energy and mass balances, chemical thermodynamics, including the thermodynamics of solutions, chemical potential and chemical activity and standards states in chemical thermodynamics in addition to Gibbs phase rule including the construction and use of phase equilbria for single, two and multi-component systems.

Learning outcome

After the coarse the student should have the following knowledge: - Calculate energy- and mass- balances for production processes of materials. - Apply the thermodynamics of solutions to analyse experimental data and to be able to use models for ideal and regular solutions on solid and liquid solutions of alloys and inorganic materials. - Calculate the chemical activity and the activity coefficient from experimental data and relate these to models for solutions. - Perform simple calculations of binary phase diagrams by the use of ideal and regular solution models. - Use the Gibbs phase rule and the principles for the construction of phase diagram based on experimental data for single, binary and multi component systems including predominance diagrams. - Extract information about phase equilbria from phase diagrams, which is of relevance to production and application of materials with focus on metals, alloys and inorganic materials.

Learning methods and activities

The course is taught through lectures and exercises. HSC Chemistry will be used to find and calculate thermodynamic values. Two semester tests and 80% of the exercises must be approved. The final is given by a letter grade based on one final exam. The teaching is given in English and the Examination papers is given in English and Norwegian. Students are free to choose Norwegian or English for written assessments. The total work effort is estimated to 200 hours.

Compulsory assignments

  • Semester tests
  • Exercises

Further on evaluation

If fail or retake, it is the written final exam you are taking again as long as the compulsory activities are approved.

re-sit exam can be changed from written to oral examination
