| Course abstract | |
| The physics course is studied in lectures, laboratory work and self-study. The course deals with important physics topics in the food sector. The nature of the physical factors and processes affecting food and used to assess food quality is explained. Students shall familiarize themselves with those laws of physics that determine the course and results of food processing, storage and control processes. The mechanisms for spreading and interacting environmental physical factors, including pressure, temperature, electromagnetic radiation and others, are explained. | |
| Learning outcomes and their assessment | |
| Students gain knowledge about the regularities considered in the physics course and a critical understanding of their applicability to describe real processes considered in their specialty – lectures, 1st, 2nd and 3th theory tests;
Skills to perform measurements of physical quantities and apply knowledge in calculations in work and research in the food industry, to summarize and analytically describe the results – laboratory and practical works; During the course students acquire competencies to evaluate the results of measurements and calculations, solutions to problems and to understand the impact of their professional activities on the environment – laboratory work, especially their defense. |

| Requirements for awarding credit points | |
| The written exam consists of two parts:
- theory: detailed answers to 5 questions (50%) - Practical part: 3 tasks to be solved (50%) All laboratory work must be counted. |
|
| Description of the organization and tasks of students’ independent work | |
| 1. Preparation for laboratory works (8 works), processing, design and evaluation of measurement results
2. Solving tasks (30 tasks) 3. Preparation for theory tests |
|
| Criteria for Evaluating Learning Outcomes | |
| During the course, 3 theory tests and 3 task tests are written (up to 10 points can be obtained for each). At the end of the semester, it is allowed to write if it is not written on time, or to rewrite it if you want to improve the grade, one theory test and one task test. 8 laboratory works must be developed and defended (up to 30 points can be obtained for them in total). If the student has received at least 50 points for the whole, then the exam may not be taken by determining the exam mark according to the number of points obtained. | |
