What is the freezing point of water in degrees Celsius?

The freezing point of water in degrees Celsius is a well-established scientific fact, recognized universally in the metric system. Water freezes at 0 degrees Celsius, which means that, at this temperature, water molecules come together to form solid ice. This key point serves as a reference in the Celsius temperature scale, making it a fundamental aspect of temperature measurement in various scientific and practical applications.

The other options represent temperatures at which water does not freeze. For instance, 10 degrees Celsius is a temperature above freezing, while 32 degrees Fahrenheit is the equivalent freezing point in the Fahrenheit scale, and 100 degrees Celsius is the boiling point of water at standard atmospheric pressure. These facts highlight the significance of 0 degrees Celsius as the correct answer, reinforcing its role as a crucial marker in thermodynamics and physical science.
