cohesion
if you are doing a science project......you might wanna try diffrent liquids on the effect of (surface tension).... milk water juice paperclip water is best for the atraction of ST. milk and the juice is what reduces ST the best The body contains a natural surface tension reducing substance called surfactant.It is found in the lungs and prevents the lungs from collapsing due to surface tension when you exhale
The surface tension of water keeps the needle afloat. Water molecules at the surface create a cohesive force acting inward, allowing the needle to sit on top without sinking.
The hydrogen bonding between water molecules best accounts for these unique properties. Hydrogen bonding is a strong intermolecular force that occurs between the slightly positive hydrogen atoms of one water molecule and the slightly negative oxygen atoms of neighboring water molecules. This bonding leads to high boiling point, high surface tension, and low vapor pressure in water.
Water is able to stick to the side of glass due to adhesion, which is the attractive force between water molecules and the molecules of the glass surface. This is also aided by the polar nature of water molecules, which allows them to form hydrogen bonds with the molecules in the glass, creating surface tension that holds the water in place.
Adhesion and cohesion are physical properties of water that are caused by water's polarity. This, in turn, is caused by the shape of the water molecule, which forms a partial difference in charge across the length of that molecule, causing intermolecular attractions between water molecules. It also explains surface tension, the fact that water expands when it freezes, and 6-sided snowflakes.
Water in conditions of free fall or no gravity forms spheres for two reasons:the mass of the water has a small gravitational effect which pulls the water into the most "economic shape." This is a sphere. In short all the water wants to get to be as close to the center of the water glob as possible, The mathematics dictate that a sphere best solves this requirement.the surface of water exhibits "surface tension" due to the orientation of the hydrogen bonding between molecules. The droplet of water as this "skin" of bound water all around it (like the skin f a balloon. The tension on the molecules in the skin equalize out. The most equal arrangement for the molecules is when the droplet becomes a sphere.

The cohesive forces in water resulting from hydrogen bonds cause the molecules at the surface of the water to be pulled downward into the liquid. As a result, water acts as if it has a thin "skin" on it's surface. You can observe water's surface tension by slightly overfilling a drinking glass with water. The water will appear to bulge over the rim of the glass.
As a water molecule in a glass of water, I would be constantly interacting through hydrogen bonding with the surrounding water molecules, creating a cohesive network that gives water its unique properties. We would be attracted to each other, forming a dynamic and ever-changing structure.
