How is water able to be adhesive and cohesive
Did you know?
WebThere are two forces at play in adhesive bonding: adhesion and cohesion - each also, at the molecular level, described as Van der Waals force. Types of Failure: Substrate, Adhesion, and Cohesion 1. Substrate or backing failure The substrate is weaker than the forces transferred to it by adhesive and cohesive bonds. WebThis is observed when water “climbs” up a straw placed in a glass of water. You will notice that the water appears to be higher on the sides of the straw than in the middle. This is because the water molecules are attracted to the straw and therefore adhere to it. Cohesive and adhesive forces are important for sustaining life.
