Water exists as solid liquid and gas at its triple point

At zero point zero one degrees Celsius and specific pressure water coexists in three states

The triple point of a substance is the precise temperature and pressure at which its solid, liquid, and vapour phases reach thermodynamic equilibrium. For pure water, this occurs at zero point zero one degrees Celsius and a pressure of about 612 pascals. At this exact point, boiling water, ice cubes, and water vapour can stably exist together.

Water exists as solid liquid and gas at its triple point: the short answers

Where does this come from, and can I check it?
At zero point zero one degrees Celsius and specific pressure water coexists in three states. The figure is taken from NIST, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
Is this really a science fact?
Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
What else can I read about it?
The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
