What is the boiling point of water in Kelvin?

The boiling point of water is defined as the temperature at which it transitions from a liquid to a gas, occurring at 100 degrees Celsius under standard atmospheric pressure. To convert this temperature into Kelvin, you use the formula:

[ K = °C + 273.15 ]

So, for water boiling at 100 degrees Celsius, the calculation would be:

[ 100 + 273.15 = 373.15 , K ]

Typically, this is rounded to 373 K. Therefore, 373 K is the correct representation of the boiling point of water in the Kelvin scale.

The other options do not represent the boiling point correctly; 0 K refers to absolute zero, which is the lowest possible temperature where all molecular motion stops. Meanwhile, 100 K represents a much lower temperature than the boiling point of water, and 273 K corresponds to the freezing point of water, making these options inaccurate in the context of the boiling point of water.
