Water Lab Conclusion
In conclusion, after conducting the lab, the emergent properties of water were tested and proved. These trials and experiments were able to verify the adhesion, cohesion, polarity, temperature stabilization, solvency, and density changes exhibited by water.
During the glass and wax paper lab, we observed the adhesive properties of water. When a droplet of water touched the glass, it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also, when the glass and wax sheets were flipped, the water remained on the glass and fell off the wax paper. This is due to adhesion; the water molecules stuck to the glass molecules and prevented the droplet from falling when the glass was turned upside down. Water is polar. Its electrons are unevenly distributed among the molecule with two unshared electron pairs on the oxygen atom. The hydrogen atoms align themselves along one side of the oxygen atom, causing a slightly positive and slightly negative side. This causes a dipole to occur. Since glass is also polar, the water and the glass will be attracted to each other because of their positive and negative charges. In real life, adhesive properties are vital for the survival of plants. Water molecules will adhere themselves to cellular membranes of plants and move up the plant to provide nutrients. Without adhesion, all the water will remain in the ground as gravity pulls down on it.
In addition to adhesion, water molecules can also exhibit cohesion. As referenced in the paragraph above, when the water droplet touched the wax paper, the water did not disperse. Instead, it remained in its droplet form. This is because water is highly cohesive; it is attracted to itself. The reason it stays in droplet form is because the positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms. Therefore, when you have to water molecules, they will instantly be attracted to each other because of the charges. Since wax

    Why is surface tension associated with cohesion and not adhesion? At the surface of the water, there is an ordered arrangement of water molecules that are hydrogen-bonded to each other and to the water BELOW, not the air above the water. This has a result of pulling the water molecules “down” away from the air-water interface.…

    In mini-lab 1, water was dropped onto the flat surface of a penny until the surface tension of the water was broken. 50 drops were able to be put onto the penny surface, with 51 drops of water being the point at which the hydrogen bonds of the water droplets that had created surface tension prior to drop number 51 failed to keep the surface tension, and the water spilt over the edges of the penny. This number of drops on the penny, 50, was possible because of cohesion. Cohesion created surface tension so the water molecules form hydrogen bonds of a greater strength with the water molecules around them. Cohesion is when a water molecule’s positive hydrogen end bonds with the negative oxygen end of another water…
