It's been a while since I took a chem course, but I thought gases are
normally in that state, while vapors arise from liquids. Gasoline, for
example, is normally a liquid, but it releases vapors.

Technically, gases expand and contract under pressure and spread
uniformly through a cylinder. Vapors don't do that.

Water vapor is the same. The rest of the gases (particularly nitrogen,
which makes up most of the atmosphere) suck up the water vapor and we
call it humidity. (water vapor also won't compress)

Where did you guys study physics? I really want to know so my grandkids
don't go there by accident.


Probably the same place you did - we just didn't sleep through it.

Your physics class covered "vapor" where "Technically, gases expand and
contract under pressure and spread uniformly through a cylinder. Vapors
don't do that."?
