What is the boiling point on the Kelvin scale?

The boiling point of water at standard atmospheric pressure is commonly known to be 100 degrees Celsius. To convert this temperature from Celsius to Kelvin, you use the formula:

( K = °C + 273.15 )

Applying this conversion:

( K = 100 + 273.15 = 373.15 )

Rounding this, it is generally accepted that the boiling point of water is approximately 373 K at standard atmospheric pressure. This value is significant in thermodynamics and engineering, as it serves as a reference point for various processes involving heat transfer, boiling, and phase changes.

The other options provided reflect temperatures that do not conform to the boiling point of pure water under standard conditions. Thus, understanding the Kelvin scale and its relationship to Celsius is fundamental in the context of power engineering and thermodynamics, making this answer vital for any related calculations or applications.
