At what temperature does water boil?

Water boils at a temperature of 212 degrees Fahrenheit under standard atmospheric pressure. This is an important point of reference in both scientific contexts and practical applications, such as cooking and various industrial processes. The boiling point of water can vary depending on altitude and the surrounding atmospheric pressure, but at sea level, the established boiling point remains at 212°F.

While 100 degrees Celsius is also the boiling point of water, it is directly equivalent to 212 degrees Fahrenheit, reinforcing that choice B is the correct answer for this question focusing on the Fahrenheit scale. The other temperatures listed, such as 320 degrees Fahrenheit or 150 degrees Celsius, do not represent the boiling point of water at standard conditions, making them incorrect choices.
