Understand that the boiling point of a substance is the temperature at which its vapor pressure equals the external pressure, causing it to change from liquid to gas.
Recognize that the standard atmospheric pressure is 1 atm (or 101.3 kPa), which is the pressure at sea level.
Recall that the boiling point of water at 1 atm pressure is commonly known to be 100 degrees Celsius.
Convert the boiling point from Celsius to Kelvin using the formula: \(T(K) = T(^\circ C) + 273.15\).
Apply the conversion to find the boiling point of water in Kelvin: \(100 + 273.15 = 373.15\) K (approximately 373 K).
