What are surroundings in thermodynamics?

उत्तर
In thermodynamics, the surroundings include every being in the universe external to the defined system (the subject of research), defined by a border, capable of exchanging energy (heat/work) or matter with the system, effectively forming the remainder of the universe that interacts with it.
