Physical and colloid chemistry
Description: The course is devoted to the study of the physical and chemical properties of substances, as well as the patterns of their interactions in various conditions. It covers such key topics as thermodynamics, kinetics of chemical reactions, electrochemistry and properties of solutions, and also focuses on colloidal systems. This discipline helps to understand how the macroscopic properties of materials are related to their microscopic processes, which plays an important role in chemical engineering, biochemistry and other scientific and technological fields.

Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
