What in heaven's name is the "'Water Triple Point"'?
And besides all the theory behind it, could you posit an experiment to prove it?

jtbell said:Table of triple points (Wikipedia)
Factoid: the triple point of water is part of the definition of the Kelvin temperature scale. It's defined as 273.16 K, exactly.
nasu said:Not at all. The Wiki article on triple point includes a list of (some) materials with their triple points.
edit: Sorry. jtbell was faster.
fluidistic said:Apparently not the only one: . I'm having some laughs, I used youtube as a search engine for once, almost unbelievable.
Edit: both jtbell and nasu have been faster.
The Water Triple Point is a specific temperature and pressure point at which water can exist in all three states: solid, liquid, and gas. At this point, the three phases of water are in equilibrium and can coexist without any phase change occurring.
The Water Triple Point is important because it is a fundamental physical constant that can be used to define the Kelvin temperature scale. It also serves as a reference point for accurately measuring temperature and pressure in laboratory experiments.
In thermodynamics, the Water Triple Point is used as a reference point for defining the standard temperature and pressure (STP). It is also used in the calculation of phase diagrams, which show the relationship between temperature, pressure, and the state of matter for a particular substance.
The Water Triple Point is determined by measuring the temperature and pressure at which the solid, liquid, and gas phases of water can coexist in equilibrium. This is typically done using specialized equipment and precise measurement techniques.
No, the Water Triple Point is a fundamental physical constant that is not affected by external factors. It remains constant at a temperature of 273.16 K (0.01°C) and a pressure of 611.2 Pa (0.006 atm).
