In science and engineering, a system is the part of the universe that is being studied, while the environment is the remainder of the universe that lies outside the boundaries of the system. It is also known as the surroundings or neighborhood, and in thermodynamics, as the reservoir. Depending on the type of system, it may interact with the environment by exchanging mass, energy (including heat and work), linear momentum, angular momentum, electric charge, or other conserved properties. In some disciplines, such as information theory, information may also be exchanged. The environment is ignored in analysis of the system, except in regard to these interactions.

| - En ciència (especialment en termodinàmica) i enginyeria, un sistema és la part de l'univers que s'està estudiant, mentre que l'entorn és la part de l'univers que resta fora de la frontera del sistema. Segons el tipus de sistema, pot interaccionar amb l'ambient intercanviant massa, energia (incloent-hi calor i treball, quantitat de moviment, càrrega elèctrica i altres propietats conservatives. En algunes disciplines, tals com la teoria de la informació, també es pot intercanviar informació. (ca)

- Среда (в теории систем) — совокупность объектов, изменение свойств которых влияет на систему, а также тех объектов, чьи свойства меняются под воздействием поведения системы. Среда, являясь зависимым понятием, всегда рассматривается по отношению к некоторой системе и представляет собой множество всех элементов, которые не входят в данную систему, но с которыми данная система может взаимодействовать. (ru)
- In termodinamica l'ambiente esterno (o più semplicemente l'ambiente) rappresenta la parte di universo che esula dall'oggetto di studio (detto "sistema"). L'ambiente è separato dal sistema tramite una superficie, reale o immaginaria, definita contorno del sistema e attraverso la quale possono avvenire scambi di calore, lavoro, materia o quantità di moto.

- In termodinamica l'ambiente esterno (o più semplicemente l'ambiente) rappresenta la parte di universo che esula dall'oggetto di studio (detto "sistema"). L'ambiente è separato dal sistema tramite una superficie, reale o immaginaria, definita contorno del sistema e attraverso la quale possono avvenire scambi di calore, lavoro, materia o quantità di moto. A seconda del tipo di interazione tra ambiente e sistema, si possono avere i seguenti casi:
* per un sistema chiuso l'ambiente è in grado di interagire con il sistema scambiando energia, ma non materia;
* un sistema isolato non scambia né energia né materia con l'ambiente;
* con un sistema aperto potranno avvenire invece sia scambi di materia che di energia con l'ambiente. Considerando l'insieme sistema sommato all'ambiente si giunge a un sistema isolato; tale sistema rappresenta la totalità dell'universo termodinamico è non scambia né energia né materia. (it)
