As water is cooled, at what temperature do its particles become fixed?
That depends on what you mean by "fixed"... The answer could be
NOTE: We would be neglecting the fact that the molecules themselves would continue vibrating with zero-point energy
All particles have 3 types of motion: vibrational, rotational (spinning on an axis) and translational (moving from point A to point B). When water is in liquid form, it's particles are packed closely together and you may only see a small amount of rotational and translational motion.
When water cools enough to solidify (which occurs at
At absolute zero, which is
