At what temperature is water converted to steam?

• A. 100F
• B. 212F
• C. 150C
• D. 100C

Answer: (B)

Water is converted to steam at a temperature of 212°F at standard atmospheric pressure (sea level). This phase change occurs when the liquid water reaches its boiling point, allowing it to transform from a liquid to a gaseous state. The boiling point of water can vary with changes in atmospheric pressure, but at sea level, it is a widely accepted standard that 212°F corresponds to 100°C. This relationship is crucial in firefighting and emergency scenarios, where understanding the properties of water and how it behaves when heated is vital for effective operations. While water can exist as steam at lower temperatures in a vacuum or under specific conditions, the temperature of 212°F is the key reference point for typical firefighting practices and procedures, as it directly influences the use of water in extinguishing fires.
