The melting point of ice is 0 Â°C (32 Â°F; 273 K) at standard pressure; however, pure liquid water can be supercooled well below that temperature without freezing if the liquid is not mechanically disturbed. It can remain in a fluid state down to its homogeneous nucleation point of about 231 K (â42 Â°C; â44 Â°F).
Boiling Point. The boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. For water, the vapor pressure reaches the standard sea level atmospheric pressure of 760 mmHg at 100Â°C.or variations in atmospheric pressure with altitude according to the barometric formula, the boiling point at a height of m = ft above sea level (atmos. pressure mmHg). would be approximately Â°C. Notes: This calculation assumes an air temperature of 20Â°C and an average air molecule mass of 29 amu.
