At what temperature does water freezes?

Answer 1

0 Celsius, 32 F.

At 273 K or 0 degree Celsius

In Fahrenheit (written °F), the freezing point of water is 32 °F. The conversion between Fahrenheit and Celsius (formerly known as Centigrade) is: F = 9*C/5 + 32. In Celsius, the freezing point of water is 0 °C. The above answer of 32 °F can be easily deduced from this expression. The specific temperature may vary a small amount depending upon the altitude and the purity of the water.

Zero degrees Centigrade and 32 degrees Fahrenheit

Answer 2

32°F or 0°C or 273.15 K

Pressure has an effect on the freezing point (or melting point) of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point on various altitudes on earth.

It should be noted that if there are ions dissolved in the water, the freezing point will be lowered significantly due to the added solute.

Heat of Fusion

*Note that water does not actually freeze when it reaches 0° C, because it requires the removal of the "heat of fusion" (enthalpy) to change phase. Water will cool slightly below 0° and remain at that temperature until it has fully crystallized into ice.

Note: Ice crystals begin to form at 39°F (4°C) making water begin to slush. It will freeze solid at 32° F if heat continues to be lost (enthalpy of fusion).

Pure water freezes at 32 degrees Fahrenheit, which is zero degrees Celsius. The addition of any impurities such as salt or ethylene glycol (anti-freeze) will lower the freezing point.
The same temperature as ice cream 0 degrees celcius.
At standard pressure (1 atmosphere, sea level) water freezes at 32 degrees F or 0 degrees Celcius. The freezing temperature is affected by pressure as is the boiling temperature.

Answer 3

Pure water freezes at 0oC at standard atmospheric pressure (1 bar)

answ2. Due to changes in the measurement definition by BIPM, the triple point of water is 273.16 K, or 0.01oC. For all practical purposes, the first answer above is Ok

Answer 4

0°Celsius degrees

Answer 5

32 degrees farenheit and 0 degrees celcius
