Plastic Baggie and Balloon Piercing

Properties of matter - Attractive forces in matter - Adhesion and Cohesion

Physical science content focus

Attractive forces in matter - Adhesive force, acts to hold two separate bodies together (or to stick one body to another). Cohesive force, acts to hold together like or unlike atoms, ions, or molecules in a single body. However, both forces result from the same basic properties of matter. Properties such as surface tension in liquids (cohesion), and capillary action (combination of adhesion and cohesion). Hardness of a diamond results from a strong cohesive forces between the carbon atoms of which it is made. Friction between two solid bodies depends in part upon adhesion.
