Adhesion is the property of different molecules or surfaces to cling to each other. 0 Adhesion is well seen in the gynostemium of orchids, where the stamens and stigmas adhere. The strong Coulomb attraction between the molecules draws them together or makes them "sticky." For example, when water molecules stick to each other forming droplets. What is adhesion and its example? Cohesion means sticking together. Intermolecular forces act also between two dissimilar substances in contact, a phenomenon called adhesion. The surface tension produced by cohesion makes it possible for light objects to float on water without sinking (e.g., water striders walking on water). Makeup Examples of Adhesive Force 1. What are some real life examples of cohesion? Cohesion is a word that comes to us through physics, where cohesion describes particles that are the same and tend to stick together water molecules, for example. For example, if the cohesion forces between water molecules are stronger compared to the adhesion forces between them, then the individual molecules present in them will attract towards each other hence resulting in settling. Cohesion of the two paragraphs made for easier reading of the article. Dew droplets are excellent examples of this. Cohesion is the mutual attraction between like molecules that causes them to stick together. For example, surface tension in liquids results from cohesion, and capillarity results from a combination of adhesion and cohesion. Adhesion forces cause water and solid surfaces to stick, while cohesion causes water molecules to stick together, forming water droplets. Meniscus 4. Each section of the activity explains a term (cohesion, adhesion and capillary action). This is the result of cohesive forces. For example, the adhesion of water molecules to the plastic beaker causes them to cling at a higher level around the edges. Surface Tension (Add the definition of surface tension and examples in your notes) . The defining feature is that adhesion occurs between two different substances.
