At atmospheric pressure, at what temperature does water boil and turn to steam?

At atmospheric pressure, water boils and turns to steam at a temperature of 212 °F. This is a fundamental property of water that is commonly referenced in both scientific and practical contexts. The boiling point of water varies with pressure; at sea level, where atmospheric pressure is standard, the boiling point is established at 212 °F (100 °C).

This temperature is critical for many applications in engineering and industrial processes. Understanding the boiling point is vital for operations involving steam, such as in steam engines, heating systems, and various thermodynamic cycles.

The other temperature choices do not reflect the boiling point of water at atmospheric pressure; therefore, they are not applicable in this context.
