A system is a particular portion of the universe we're interested in studying that we select for analysis. This selection should be representative of the larger universe or a specific portion of it, and it must exhibit distinct features that allow us to study its behavior.
The surroundings encompass the rest of the universe that interacts with the system. This includes not only the other physical objects that are affected by the system's changes but also the effects that the system has on the surroundings.
The distinction between a system and its surroundings is crucial because the system's behavior can be vastly different from that of the surroundings. For instance, consider a closed system, in which heat and energy cannot escape, and a open system, in which the system can interact with the surroundings.
The concept of a system and its surroundings is fundamental in chemical thermodynamics, which deals with the relationships between heat, work, and energy in a system. By carefully defining the system and its surroundings, chemists can determine the changes in these quantities during chemical reactions and physical transformations
