Question

Quizplus · Accepted Answer

The temperature of boiling water at ordinary air pressure (1 atm) is 100°C, which is equivalent to 373 K on the Kelvin scale. The Kelvin scale starts at absolute zero, and the conversion from Celsius to Kelvin is done by adding 273.15. Therefore, 100°C + 273.15 = 373.15 K, which is approximately 373 K.
