3

Knowledge of the basic principles and laws of molecular physics, their mathematical formulation; mastering practical skills of using measuring instruments and experimental equipment; knowledge of general safety rules of the experimental research. Ability to estimate the orders of magnitude of the studied quantities, their accuracy and degree of reliability, calculate measurement errors and formulate conclusions; to work independently with educational, methodical, and reference literature on molecular physics.

The student must know the basic laws of thermodynamics and molecular physics, the basics of error theory, and data processing. The student must be able to: apply previous knowledge on the presentation of experimental data, rules for calculating measurement errors, calculation of derivatives, and integrals, and be able to graphically construct experimentally obtained dependences. Have basic skills in working with measuring instruments; searching and analysis of tabular data, working with software for data processing, and group work.

Laboratory work

Assessment is conducted during the semester, after the performance and defense of laboratory work. To enroll in laboratory work, the student must submit a written report on the relevant laboratory work, which must contain the original experimental data, calculations - the formula and result of calculating the required value, errors, relevant graphs, conclusions about measurement methods, and obtained results, answer the basic questions on the topic of work. The final assessment is conducted in the form of a differentiated test. The student can receive a maximum of 100 points: 60 points for work during the semester and 40 points during the test.
