Abstract:

Considerable information is available showing that certain monomolecular films can greatly retard the evaporation of water, and recent studies have shown that such monomolecular films will change the temperature of the water surface. Monomolecular films have also been shown to change the surface tension and surface viscosity of an aqueous substrate. The study shows that changes in these latter two properties, apart from the monolayers effect on evaporation, can also lead to changes in the temperature of a water surface because of the effect of the film on the convective movement of surface water. It is thus apparent that the surface temperature of a layer of water will be dependent upon many environmental factors and can be influenced in several ways by the addition of a monomolecular film to the waterair interface.
