* 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure (1 atmosphere).
This is the temperature at which the vapor pressure of water equals the surrounding atmospheric pressure, allowing water to transition from a liquid to a gaseous state.
The boiling point of water can change depending on the atmospheric pressure. For example:
* At higher altitudes, where the atmospheric pressure is lower, water boils at a lower temperature.
* In a pressure cooker, the increased pressure raises the boiling point of water.
So, while the boiling point of water can be affected by external factors, it always has a specific boiling point under given conditions.
