At standard conditions, water boils at what temperature in Celsius?

At standard conditions, water boils at what temperature in Celsius?

• A. 100°C
• B. 0°C
• C. 212°C
• D. 37°C

Answer: (A)

At standard atmospheric pressure (about 1 atm, 101.3 kPa), water boils when it reaches 100°C. This is the temperature where water's vapor pressure equals the surrounding pressure, causing it to transition from liquid to gas. The other temperatures describe other states: 0°C is the freezing point, 212°C is far above the typical boiling point at standard pressure, and 37°C is normal body temperature. So 100°C is the correct boiling point under standard conditions.
