but it remains a gas or liquid that that concepts cannot explain - With all my due respect, but it seems that you have fallen into the "essentialist trap". A name is but a code used to refer to a concept. It is not a concept by itself. If you try to chose or invent a name that "explains" a thing, you are likely to fail: mostly because the name would become half a page long, or more (in the case of water, probably a book )
