Write two examples where you can see adhesion at work in the real world.

Answer 1

Sure! Here are two examples where adhesion is evident in the real world:

1. Wet Surface and Water Beads: When raindrops land on a car's windshield, they often form beads rather than spreading out completely. This is an example of adhesion at work, where the water molecules are attracted to the glass surface of the windshield. The adhesive force between the water molecules and the glass allows the droplets to cling to the surface, demonstrating how adhesion affects the behavior of liquids on solid surfaces.

2. Tape Sticking to Surfaces: When you use adhesive tape to stick two surfaces together, such as wrapping a gift or securing papers, the tape adheres to the materials due to adhesive forces. The sticky side of the tape contains a material that creates an attractive force between the tape and the surface upon contact, allowing the tape to bond temporarily. This example illustrates how adhesion functions in everyday tasks, enabling us to join materials effectively.
