Dew point more important than boiling point

    I was thinking, the critical point between the liquid and gas phases is the dew point, not the boiling point, right? Melting/freezing on the solid/liquid boundary is analogous to evaporation/condensation on the liquid/gas boundary. Boiling is something totally different, and is not possible in equilibrium.

    I'm not really puzzled by anything. I just think it's strange that we hear so much more about boiling than evaporation in early science classes

    Dew point is a line and boiling point is on one end of it. It stands out.

    Strictly speaking, "boiling point" is the temperature at which vapor pressure (of a liquid) equals one atmosphere; it's just one point on the vapor pressure curve.
