Cohesiveness of Water Lab
Cohesion is the attraction between molecules of the same substance. Adhesion is the attraction between molecules of a different substance. Water’s molecules can stick to both its own substance and a different substance making it both cohesive and adhesive. Water is a mixture of oxygen atoms, and hydrogen atoms, also known as H2O.
This lab was conducted so scientist know what substance effects the cohesiveness of water molecules. This would be important to know for people who are working with bathtubs, or pools, so they would know what substance to put in water and what not to put into water.
More clips will be held inside of the container with plain water, than the container with soapy water, therefore the water with soap will be less cohesive.
Materials in this lab include;
In this lab you will find that when is not mixed with another substance such as soap there will be more cohesiveness. Soap separates the water molecules making it harder for water molecules to stick together. More clips were held inside of the container with plain water, than the container with soapy water, therefore the water with soap will be less cohesive.
