# At What Temperature Does Water Freeze?

The melting point of water at 1 atmosphere of pressure is very close to 0 °C (32 °F, 273.15 K).
At sea level, water freezes at 0° C or 32° F.
Pure water freezes at a temperature of 0 degrees Celsius. This is for normal atmospheric pressure. The Celsius scale was defined by the freezing and boiling points of water, with 100 equal intervals (degrees) between them. Pure water will begin to freeze at 0°C, but requires the removal of additional energy to change phase into crystalline ice.
The freezing point of water is widely known to be 32 degrees Fahrenheit, or 0 degrees Celsius. Water can be prevented from freezing at this point by providing a controlled environment in a lab. Water is one of the substances that remain a liquid at room temperature.
The temperature that water freezes is 0 degrees Celsius, 273.15 Kelvin or 32 degrees Fahrenheit but this is for normal atmospheric pressure. Pressure is a contributing factor to the melting point or freezing point of water.
The temperature of freezing water is 0 ???øCelsius, or 32 ???øFahrenheit. The temperature may be lower if supercooling occurs or if there are impurities present in water. Water expands upon freezing.
