Question 3) At a temperature of 298 K, the contact angle of a drop of water on dichloroethane is 108.5°C (227.3°F). If the surface tension of the dichloroethane is 25.0 mNmˆ-1 and of the water 72.2 mNmˆ-1, determine the interfacial tension, work of adhesion, and mirroring coefficient between the water and the dichloroethane.
