What is the boiling point of water in degrees Celsius?

The boiling point of water is defined as the temperature at which it changes from liquid to gaseous form at a given atmospheric pressure. Under standard atmospheric pressure (1 atm, which is the pressure at sea level), the boiling point of pure water is 100 degrees Celsius. This temperature is significant in both scientific research and everyday cooking, as it serves as a reference point for heat and temperature measurement.

The value of 100 degrees Celsius represents the point where the vapor pressure of the liquid equals the surrounding pressure, allowing bubbles of steam to form within the liquid, which is characteristic of boiling. This knowledge is foundational in the study of thermodynamics and phase changes, making it essential for understanding various scientific and practical applications.
