Flexi Says: Things become wet when the water molecules adhere to the surfaces of solids. Water itself cannot be classified as wet. The hydrogen bonds of the polar molecules create properties known as cohesion and adhesion. Cohesion is the tendency of water molecules to stick together, which helps the molecules form droplets or small pools on surfaces. Adhesion is the property of water that enables the bonding of the water molecules to surfaces. In this process, the hydrogen bonds of water molecules rapidly and frequently break and reform, which allows some of the water molecules to bond to a different substance (a surface).
