How do you define "closed" and "isolated"? In fact, this is the first time I'm hearing of a distinction between the two terms. In my experience, they are used synonymously.
- Hayarotle 5y agoIn a closed system, matter cannot be exchanged between the system and the surroundings, but energy can be exchanged (in form of work or heat). In an isolated system, neither matter nor energy can be exchanged [1]. Those are the definitions used in thermodynamics, but they might be conflated into a single concept in other contexts/disciplines [1] http://www.projects.bucknell.edu/LearnThermo/pages/Other%20Topics/open-and-closed-systems-simulations.html http://www.projects.bucknell.edu/LearnThermo/pages/Other%20T...
