At what temperature does pure water freeze, measured in degrees Celsius?

Pure water freezes at 0 degrees Celsius under standard atmospheric pressure. This temperature is a fundamental reference point in the Celsius temperature scale, which is widely used around the world. At 0 degrees Celsius, water molecules slow down enough that they form a solid structure, resulting in ice. This is an important concept in both everyday life and scientific contexts, as it serves as a baseline for many temperature-related calculations and discussions regarding states of matter. Understanding this temperature is crucial for fields such as meteorology, environmental science, and even culinary arts, where precise temperature measurements are vital.
