#### Course Objective

The course aims to give thermodynamical properties, the relationship between the phase equilibrium diagrams and free energy curves of solutions and other phases. It demonsrates how to calculate some properties using measurable properties.

#### Learning Outcomes of the Course Unit

 1 Explain the formation and mixture properties of solutions and alloys, 2 Determine the partial molar properties of solutions using solution properties, 3 Calculate thermodynamic properties of ideal, regular and non regular solutions, 4 Evaluate the relationship between the free energy - composition curves and phase diagrams, 5 Specify the experimental methods of obtaining thermodynamic data to be used in calculations of properties, 6 Recognise the criteria for equilibrium between a solution and environment.

#### Further Notes About Assessment Methods

Midterm exams and final exams related to learning outcomes are given as usual closed book and closed note written exams. Homework results will also be included in the term time assessment.

#### Assessment Criteria

Midterm exam results and homework grades will make up term time grade, which will be added to the contribution of the final exam result to determine the course grade.

English

#### Course Policies and Rules

Students must attend the lecture periods (minimum attendance requirement is 70%). The use of MP3 player, cell phone and ear phones are not allowed during class and during exams. The programmable high memory calculators should not be used during exams.
Homework must be handed in on the due date. Any copying evidence in homework and exams will result in a grade of zero, and lead to disciplinary action.
