The textbook includes didactic material on the basic discipline "Computer Science", section "Programming of data processing in spreadsheets" . The paper uses an algorithmic approach to solving applied problems in the MS Excel 2010 package on the example of the problems of the physics section "Gas kinetics": more attention is paid to setting the problem in terms of applied information and algorithmizing its solution in electronic tables. The training manual is intended for students of all forms of education in the areas of bachelor's training and specialization: 140100 - Thermal power engineering and heat engineering ; 140400 Electricity and Electrical Engineering ; 230400 Information Systems and Technologies ; 141403 - Nuclear power plants: design, operation and engineering .
