Water boils at a temperature of 100 degrees Celsius at sea level, which is equivalent to 212 degrees Fahrenheit. This boiling point can vary depending on atmospheric pressure; for example, at higher altitudes where atmospheric pressure is lower, water will boil at a lower temperature. Boiling is the process where water turns from a liquid state to vapor, and it is a critical aspect of cooking and scientific experiments. Understanding the boiling point of water is essential for various cooking techniques and for processes that involve temperature regulation.
