"If you have water molecule in gaseous state,
after heating it significantly,
you will turn it to gaseous hydrogen and gaseous oxygen,
after heating it even more,
you will turn them to hydrogen plasma and oxygen plasma state."
ok it becomes liquid again and becomes solid later on, thanks.
Still i have no answer to the ionization issue of the molecule in gas state, for example h2o in gas state. When you ionize the oxygen atom and freeze the molecule rapidly it will become liquid you say. So no other phenomenon will occur, i doubt it is the same. The ionization process activates the elektrons and the elektrons activate the protons, so maybe a different liquid form will be gained, like rainwater and damp visible for the human eye.
I understand that at the boiling point all atoms reach a point of changing. For myself i can imagine that the force needed, the temperature needed to reach this point, can change when oxygen atoms are ionized with a ionisator. Maybe you just need -100 refrigator instead of -300 for example.
