Gustav Tammann determined that this condition exists at several different points for water; for ice III it occurs at about 251 on the kelvin scale.
Gustav Tammann determined that this condition exists at several different points for water; for ice III it occurs at about 251 on the kelvin scale. Taking the inverse that this condition exists for water defines the unit of the Kelvin scale; extremely precise thermometers are still calibrated using this condition. Gibbs phase rule implies that a pure substance in this condition will have zero degrees of freedom. A system with p phases will have p choose 3 number of these points; one of them for water exists at .01 degrees Celsius and 611 Pascals. For 10 points, name this point on a phase diagram where a substance can exist as a solid, liquid and gas.
