The Properties of Water!! by: Gianna Sannicandro

Water is essential to human life and has a variety of properties. These properties include adhesion, cohesion, surface tension, and polarity.

Water is a made up of two hydrogen atoms and one oxygen atom, which creates the formula H2O
These water droplets exhibit cohesion and adhesion because the water molecules stick together to make droplets, and the droplets stick to the surface of the leaf.

Cohesion is the tendency of like molecules, particularly water molecules, to stick together. This can be caused by hydrogen bonds, which make water want to come together.

Adhesion is the action or process of sticking to a surface or object.

The paper clip is able to float on the water without initially sinking because of surface tension.

Surface tension is the elastic like force existing in the surface of a liquid tending to minimize the area of the surface. This property allows objects such as paperclips to float on the surface of water, if not disturbed by outside forces. Such as pressing your finger down on the object and making in sink.

Polarity is demonstrated when there are two opposite sides presents. As shown in the picture above opposite sides attract and similar sides repel. This applies to the forming of hydrogen bonds because they are pieced together by placing the hydrogen and oxygen atom next to each other creating an attraction.
