Unformatted text preview: Cohesion and Adhesion By: Lanasia Gatlin & Ty-Mire Cohesion Definition is the property of like molecules (of the same substance) to stick to each other due to mutual attraction.Adhesion is the property of different molecules or surfaces to cling to each other. Adhesion and cohesion are terms that are often confused although these subjects are discussed in many standard texts in dental biomaterials science [1–3].There are also many excellent texts and monographs on adhesion, cohesion, and interfacial reactions [4–6] together with a comprehensive treatment in the on-line encyclopedia, Wikipedia.Since adhesion and cohesion … Example- update record int the database and send it to the printer. It's usually observed in some liquids, but it's … Adhesion and cohesion are tailored to the application. This property of liquids is known as capillarity. Capillarity is the tendency of liquids to rise and fall in a tube.
