Correct option is A
The correct answer is (a) 100° C
Explanation:
• The boiling point of water at standard atmospheric pressure (1 atmosphere) is 100° Celsius.
• At this temperature, water changes from a liquid to a gas (steam or vapor).
• The boiling point can vary slightly with changes in atmospheric pressure, such as at higher altitudes, but under normal conditions, it is 100° C.
Information Booster:
• The boiling point of water is a fundamental reference point in the Celsius scale and is used for many scientific calculations.
• Water boils at 212° Fahrenheit and 373 K (Kelvin scale).
