Whoopsy. I left out the main part of the question. The molecule(s) I seek has a different name for each state (ice, water, vapor.)
Ice - when I approach a hot babe at the pub.
Liquid - when I find out she is drunk.
Vapour - when she realize that I'm not going to pay for her next drink.

Therefore I wrote "more or less".
I suppose that even CO2 has its liquid phase in certain pressures...
They are quite interseting and quite strange some of them.
Check out the phase daigram for nicotine it's quite odd.
The phase diagrams here are for one component systems and are very easy to understand.
Things get tricky when you have 2 or 3 component phase diagrams!

Solid, Liquid and Gas states are a relationship between internal energies (at the atomic and molecular scale) which is temperature, and the bonds that hold the individual molecules together (such as hydrogen bonds).
Every substance has a B.E.C., solid, liquid, gas and plasma state.
Thats right, 5 states of matter.
Not all substances have reached ...[text shortened]... I know) but theoretically it is possible for any type of matter to reach any of those 5 states.
That make 7!

Aren't they all, more or less?

The molecule configuration changes during change of state (e.g evaporation) The intermolecular bonds of the molecule berak and so its no longer H2O but its seperated into hydrogen and oxygen.
People like you make me feel secure. They don't dare fire a science teacher with a science degree who actually knows science.
