Laboratory experiments are related to the essential sections of the contents of the physical chemistry I lecture. The students work in two person groups under supervision of a teaching assistant. 10 (level B) or 6 (level A) experiments are to be completed by every group. The experiments are divided into two thematic sections: I – thermodynamics and phase equilibria, II – termochemistry and properties of the matter. In every section the experiments are strictly related to the scientific topic of the section. Time of a single experiment – 5 hrs.
The aim of the course is to provide students with knowledge of methods and equipment used in determination of basic properties of physical systems. These properties include viscosity, surface tension, dipole momentum and osmotic pressure. The students investigate phase equilibria in single component and binary systems, the energetic effects of phase transitions are determined. An user written, non-commercial computer software, is used for determination of thermodynamic functions of binary systems of non-electrolytes (Universal Functional Activity Coefficient – UNIFAC method).
Laboratory – 60 hrs.
Individual preparation to each experiment– 10 x 4 hrs. = 40 hrs.
Evaluation of the results and final report preparation - 10 x 4 hrs. = 40 hrs.
Total - ca.140 hrs.

|Assessment methods and assessment criteria:||
The students must pass an entrance test before being eligible for starting the experiment. The entrance test checks students' knowledge of: (i) the experiment fundamentals, (ii) the purpose of the experiment, (iii) methods of the measurements; and (iv) equipment to be used in the experiment. Evaluated results of the experiment must be reported to teaching assistant in a written form as a final report.
Once all the experiments in a specified thematic section have been completed, the students take midterm exam covering scientific topics of the section. All the experiments must be completed and all the final reports must be evaluated positively in order to be eligible to take the midterm exam.
To obtain the course credit the student must: (i) complete all the laboratories; (ii) all the final reports must be evaluated positively; and (iii) the student must pass both midterm exams.
entrance test – 0,5-3 points
Final report - 0 –2 points
Midterm exam - 0 – 20 points (minimum 10 points required for passing)
The points earned for the experiments are averaged. Maximum number of the points to be earned for each experiment: 5
Total number of points earned in both midterm exams and average number of points for the experiments will determine the final grade.
Maximum number of points to be earned in the semester: 50
Conversion between points and grades:
points: 26,0 – 31,5 grade: 3
31,6 – 36,5 grade: 3+
36,6 – 41,5 grade: 4
41,6 – 46,5 grade: 4+
46,6 – 50 grade: 5
