The article considers the basic principles of the first law of thermodynamics, which establishes the law of conservation of energy in thermodynamic systems. It discusses how this law relates work, heat and internal energy, as well as its importance for understanding the processes occurring in various physical systems. Particular attention is paid to the concept of enthalpy as an important thermodynamic function, which allows analyzing processes at constant pressure. The article focuses on the practical application of the first law of thermodynamics and enthalpy in chemical reactions, heat exchange processes and engineering calculations. It also considers modern approaches to the study of thermodynamic properties of substances and their application in the development of new technologies, such as alternative energy sources and heat management systems. The importance of a deep understanding of the first law of thermodynamics and enthalpy for the further development of the theory of thermodynamics and its practical application in science and technology is emphasized.
