Stack Exchange sites can get closed if the become inactive.. The site contents are removed and are available only as data dumps.
However, chat rooms have a more liberal retention policy: they are kept permanently if they got at least 15 messages by 2 users.
So what happens to chat rooms associated with sites that get deleted? I think each chat room has to have a parent site, but these rooms' parent sites will cease to exist.
