Question:
Why is syrup sticky?
Answer:
Cohesion is the force between like molecules, such as between two water molecules or between molecules in syrup. One syrup molecule sticks to another syrup molecule because of cohesion.
If you want to know why syrup sticks to your fingers, it is because of adhesion, which is the force between different kinds of molecules. The greater the adhesion between the two substances, the “sticker” the substance.
Adhesives are substances that are used to stick different substances together. For example, glue is an adhesive used to stick paper pieces together.
