What constant temperature does water freeze at, measured in Kelvin?

Water freezes at 273 Kelvin, which is the absolute temperature equivalent to 0 degrees Celsius. This is significant in the study of thermodynamics and phase changes because the freezing point of water serves as a key reference point in defining the Kelvin scale. The Kelvin scale starts at absolute zero, which is 0K, and increments units in the same way that degrees Celsius does. Knowing that water's freezing point is 273K allows us to understand the behavior and thermal dynamics of water as it transitions from liquid to solid. This temperature is important in scientific measurements and calculations involving thermal energy and temperature conversions.
