What is the boiling point of water on the Fahrenheit scale?
Last Updated:
A100°F
B180°F
C200°F
D212°F
Correct Answer: 212°FYour Answer: D
Explanation
The boiling point of water is a key fixed point on temperature scales. Option A (100°F) is incorrect — 100°F corresponds to approximately 37.8°C, which is close to normal human body temperature but is NOT the boiling point of water. 100°C (not 100°F) is the boiling point on the Celsius scale. Students frequently confuse 100°C with 100°F. Option B (180°F) is incorrect — 180 is significant on the Fahrenheit scale because it is the total number of divisions between the freezing point (32°F) and boiling point (212°F) of water: 212 - 32 = 180. Option C (200°F) is incorrect — 200°F ≈ 93.3°C, which is below the boiling point of water. Water would not yet be boiling at 200°F at standard atmospheric pressure. Option D (212°F) is CORRECT — the boiling point of pure water at standard atmospheric pressure (1 atm) on the Fahrenheit scale is 212°F. This corresponds to 100°C and 373.15 K. The Fahrenheit scale has 180 divisions between 32°F (freezing) and 212°F (boiling).

What is heat in physics?
Heat is a form of energy that transfers between objects or systems due to a temperature difference, moving from a hotter body to a cooler one until thermal equilibrium is reached.
