The triple point of a substance is the temperature and pressure at which three phases (gas, liquid, and solid) of that substance may coexist in thermodynamic equilibrium.
The triple point of water is the pressure and temperature at which pure water, pure ice, and pure water vapour can coexist in a stable equilibrium occurs at exactly 273.16 kelvins (0.01 °C) and a pressure of 611.73 pascals (ca. 6.1173 millibars, 0.0060373057 atm).
At that point, it is possible to change all of the substance to ice, water, or vapour by making infinitesimally small changes in pressure and temperature.

Triple Point Of Water

The single combination of pressure and temperature at which pure water, pure ice, and pure water vapour can coexist in a stable equilibrium occurs at exactly 273.16 kelvins (0.01 °C) and a pressure of 611.73 pascals.
NOTE-
At a constant pressure higher than the triple point, heating ice necessarily passes from ice to liquid then to steam.

Triple point of a substance is a temperature where it is possible to change the state of the substance to solid, liquid or gas with a slight change in pressure or temperature. Triple point of water occurs at a pressure of 611.73, it is 0.01 degrees celcius.

It is the temperature where water can exist in its three states - solid (ice), liquid and gas (water vapour) with all three states being stable . It is a little above 0°C. 0.4°C I think but I will take correction on that.

As stated the point where gas, solid and liquid all exist. For water it is 32 F.

It is less than 1 degree centigrade/celsius above the freezing point of water (0 degrees centigrade/celsius) I remember something like 0.1 degrees above 0

4 deg. celcius.
at this temperature, all the three states of matter, in case of water, co-exist.
