What is the freezing point of water in degrees Celsius?

The freezing point of water is defined as the temperature at which it transitions from a liquid to a solid state. In degrees Celsius, this temperature is 0 degrees. This is a standard measurement in science, particularly in the context of temperature scales. The Celsius scale was designed with the freezing point of water at 0 degrees and the boiling point at 100 degrees, making it a straightforward system for scientific measurements.

The other options represent temperatures in different contexts: 32 degrees is the freezing point of water on the Fahrenheit scale, 100 degrees is the boiling point of water in Celsius, and 212 degrees is the boiling point of water on the Fahrenheit scale. Understanding these variations helps clarify why 0 degrees Celsius is recognized as the freezing point of water in the Celsius system.
