Concept:Boiling point is the temperature at which a liquid turns into vapour, and it depends on atmospheric pressure. At sea level, with standard pressure, water has a fixed boiling point.
Explanation:The boiling point of water at sea level is 212 °F, which equals 100 °C.
This temperature is measured under standard atmospheric pressure of 1 atmosphere (101.325 kPa).
At this point, water changes from liquid to gas (steam).
If altitude increases, pressure drops, and water boils at a lower temperature (e.g., 203 °F at 5,000 feet).
Understanding this helps in cooking, sterilization, and scientific measurements.
Answer:C. 212 °F
