My theory? No; subatomic vibration has nothing directly to do with freezing water's expansion. I believe your answer involves density. The work being
performed by the energy being removed is to force the H2O molecules into a more-rigid crystalline structure (ice), which is physically larger than the
fluid, uncrystallized state. The energy being removed sort of "sucks" the molecules apart, per se. The volume expands with no change in mass as the
brownian motion goes away, which lowers the density and exerts mechanical force in all directions that, if restrained, tries to overcome its
container. Liquid water expands both
when frozen or boiled, but far more so when boiled. Or plas- plas, ummm, plasmated? Plasmized? (There
ought to be a word.) Water can only expand a small amount when frozen, but it is inexorable... like, ummm... it's not easy coming up with an analogy;
it's quite a unique feature of water that it does this, not much else does. Water gets bigger when it freezes because of the shape of its molecules,
and there is an upper limit to size, unlike when it gets hotter. No matter how much colder ice gets, it doesn't expand further; that's a one-off when
crossing the freezing point, and it's due to the molecules pushing each other into a crystalline configuration and locking together like that,
providing rigidity. Analogy, analogy, simile, metaphor, what, what...
Jenga!! Yes, that's it. As you pull little blocks out of the bottom and stack them on top, the tower's mass stays the same but the density drops as it
takes up more space. It's... sort of the same as water freezing, as close as I can think of right now. Nothing to do with particle vibrations,
the energy which exerts the pressure is electromagnetic, the energy in each electron, their like charges trying to repel each other.
Ultimately, all energy starts with vacuum energy, the energy that creates each particle and gives it mass, charge, and spin. Temperature doesn't
affect those three fundamental properties. Perhaps your answer lies along those lines.
