What is the boiling point of water on the Kelvin scale?

• A. 273 K
• B. 310 K
• C. 373 K
• D. 100 K

Answer: (C)

The boiling point of water in Kelvin is 373 K. The Kelvin scale is an absolute temperature scale where 0 K (absolute zero) corresponds to -273.15°C. To convert the boiling point of water from Celsius to Kelvin, you add 273.15 to the Celsius temperature. The boiling point of water at standard atmospheric pressure is 100°C, so when you add 273.15 to 100, you get approximately 373.15 K, which is effectively rounded to 373 K for most practical purposes. This understanding of the conversion between Celsius and Kelvin is crucial in scientific contexts where temperatures need to be expressed in absolute terms, which is only feasible on the Kelvin scale.
