298K

298 Kelvin (298 K) is a temperature commonly used as a standard reference point in scientific measurements. It is equivalent to 24.85 °C or 76.53 °F. This temperature is often referred to as “room temperature” because it approximates typical indoor conditions for many laboratories, offices, and living spaces.

In chemistry, 298 K is the temperature at which many thermodynamic tables are constructed; reaction rate constants, equilibrium constants, and thermodynamic properties such as Gibbs free energy and enthalpy are frequently reported at this value. It is also the standard temperature used in the ideal gas law when calculating molar volumes; at 298 K and a pressure of 1 atm the molar volume of an ideal gas is about 22.7 L.

Engineering and physics utilize 298 K for various standard tests and calibrations, especially in environmental and materials science where air properties are evaluated at a reference temperature. The use of a common reference temperature facilitates comparison of data across different studies and ensures consistency in scientific literature.

298 K remains a convenient and widely accepted benchmark because it corresponds to a relatively stable, easily reproducible condition for experiments and industrial processes.
