Underlying physics of partial pressures

  1. Jun 7, 2012 #1
    How do gases exist at partial pressures in a mixture. Moisture in the air is superheated steam, yet at a temperature well below atmospheric boiling point, implying that the moisture in the air is at very low pressures. How does it maintain this state?

    Maybe it hasn't reached equilibrium yet, that's gotta be in the thermo book.

    Evaporation is not (yet) boiling, vapours is not steam. An example of slightly superheated steam in everyday life is the pressurised steam over the boiling water in a closed tea kettle.
