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).
Conventionally, the water temperature at which water boils is considered to be 100 degrees Celsius or 212 degress Fahrenheit. However, these numbers are only valid at sea level. As barometric pressure changes so too does the boiling point of water. For instance, as elevation increases the boiling point lowers. On the top of Mount Everest, for example, boiling water is possible at a water temperature of 68 degrees Celsius or 154 degrees Fahrenheit. Conversely, in deep ocean vents, water can be much hotter than that without boiling.
