The temperature of boiling water at ordinary air pressure on the absolute scale-Kelvin-is:
A) 273 K.
B) 212 K.
C) 100 K.
D) 373 K.

Question

Quizplus · Accepted Answer

The boiling point of water on the Kelvin scale is 373 K. This is because the Kelvin scale is based on absolute zero, which is -273°C. Therefore, 0°C is equal to 273 K, and the boiling point of water at 100°C is equal to 373 K. A is incorrect because 273 K is equivalent to 0°C, which is the freezing point of water. B and C are also incorrect because they are too low to be the boiling point of water.
