Why does water evaporate even below its boiling point?

  1. Nov 27, 2005 #1
    why does water evaporate even below its boiling point? is it because the bonds between particles aren't strong (while particles in water moves) thus some escape periodically or does it have something to do with convection currents?

    Convection may speed up the evaporation process by, e.g., increasing the surface area but the main effect is that some of the water molecules near the surface are moving at speeds sufficient to let them "escape." In effect, they are the hotter molecules and leave the cooler ones behind.
