Which set of values corresponds to the boiling point of water in Celsius, Fahrenheit, and Kelvin?

• A. 100 C, 212 F, 373 K
• B. 0 C, 32 F, 273 K
• C. 110 C, 230 F, 383 K
• D. 120 C, 248 F, 393 K

Answer: (A)

The boiling point of water at standard atmospheric pressure is 100 °C. Converting 100 °C to Fahrenheit using F = C × 9/5 + 32 gives 212 °F. Converting to Kelvin by adding 273.15 yields 373.15 K, commonly rounded to 373 K. So the set 100 °C, 212 °F, 373 K matches the boiling point of water. The other sets reflect either the freezing point or incorrect conversions, so they don’t describe the boiling point.
