OPEN SYSTEM |
|
Definition
* Any system that exchanges both matter & energy with its surroundings
* A perfect example of an open system is a living organism such as a human being. We actively interact with our environment, which results in changes to both the environment and us. For example, we eat to acquire energy. We are subject to the sun's radiation and the climate of our planet |

Definition
* Everything outside of a system
* Surroundings are the area around a given physical or geographical point or place. The exact definition depends on the field. Often, the simplifying assumptions are that energy and matter may move freely within the surroundings, and that the surroundings have a uniform composition |
