The article discusses the formation of creative thinking of students in the study of Thermodynamics. It is shown that when studying cyclic processes occurring in gases, it is necessary to pay attention to the physical essence of the phenomena under consideration. Students will be able to explain changes in any parameters at a qualitative level if they understand the physics of the process and the teacher correctly poses a question that makes the student think creatively.

The kinetics and thermodynamics of the growth and decomposition of R134a freon hydrates have been studied. It has been established that synthesis from liquid freon and snow at atmospheric pressure is effective at temperatures below -26°C, and the process is limited by diffusion. The activation energy of hydrate decomposition was 38.7 kJ/mol, and the gas content was 40 ml/g of water. The thermodynamic parameters were determined by the DSC method and the effect of the system's background and the inhibitory effect of a eutectic solution of CaCl₂ (~25°C) on hydrate formation was shown. The process is technologically controllable and promising for use.
