Which temperature scale uses 212 as the boiling point of water?

• A. Celsius
• B. Fahrenheit
• C. Kelvin
• D. Rankine

Answer: (B)

Fahrenheit defines water’s boiling point at standard atmospheric pressure as 212 degrees. That scale also places freezing at 32 degrees, with increments sized so 212°F corresponds to 100°C. In contrast, Celsius uses 100°C for boiling, Kelvin uses 373.15 K, and Rankine uses about 671.67 R for the same condition. Since 212 is characteristic of the Fahrenheit scale, that is the appropriate choice.
