What is the Freezing Point of Water?
The Freezing Point of water is any temperature below the Melting Point!
Let’s look at the temperatures that make liquid water and water vapor freeze, and the difference in temperature scales.
There are two different scales that are used to measure temperature: Fahrenheit and Celsius.
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit, and had been used in many English-speaking parts of the world and Europe, until the metric version (Celsius) became widely adopted.
Many people erroneously say that the freezing point, in the Fahrenheit scale, is 32 °F (thirty-two degrees Fahrenheit). The distinction however, is that 32 °F is actually the melting point of water. Therefore, the freezing point of water must be below 32 °F.
The Celsius scale was developed by Anders Celsius, a Swedish astronomer, around 1742. The freezing point on the Celsius scale is 0 °C (zero degrees Celsius). As a historical side note, the Celsius scale used to actually be called the “centigrade scale”.
