What is the boiling point of water (at normal atmospheric pressure) on the Kelvin scale?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 373 K
A temperature in kelvin is found by adding 273 to the temperature in degrees Celsius. Water boils at 100 °C, so its boiling point is 100 + 273 = 373 K; 273 K is the melting point of ice (0 °C).
