In this study, we analyzed the relationship between the adhesion of two solid surfaces due to interstitial ice and the geometric dimensions of the ice. To determine the geometric dimensions of the ice, we photographed the water-solid surface interface before freezing and utilized an image analysis program. To measure the adhesive force between the two solid surfaces, we designed an experimental device that exerts shearing stress on one of the two solid surfaces that were frozen together. Through this device, we measured the force necessary to separate the two solid surfaces. Interestingly, we noted a correlation between a quantified measure of the geometric dimensions of the ice and the adhesive force per unit area of the two solid surfaces. By using the concept of practical work of adhesion to describe the adhesive force between ice and a single solid surface, we were able to present a theoretical model that explains the trends displayed by the experimental data.
