It was found that a quasi-uniform high-strength electric field causes an in
crease in the rate of the evaporation of liquids. The effect is more pronou
nced when the electrode above the water surface or an aqueous KCl solution
has positive potential (in this case, the direction of the field is the sam
e as that of atmospheric electricity). The results obtained imply that the
water molecules of the surface layer are orientated so that the oxygen atom
s point toward the gas phase.
