Tap Water Cohesion Experiment
Water has polarity. Polarity is the uneven distribution of charge. Water has cohesion, adhesion, and heat capacity. Cohesion is the attraction between molecules of the same substances. Adhesion is the force of attraction between molecules of a different substances. Heat capacity is the amount of heat it takes to raise temperature of a substance. The experiment displayed shows water can have adhesion and cohesion. The hypothesis of this experiment is if a nonpolar substance is added to water then cohesiveness will decline. When collecting the data the cohesiveness did not decline. This shows that the hypothesis has been refuted. The tap water contained sixty-two paper clips, whereas the soapy water has fifty-eight. Therefore, the amount …show more content…
The experiment did not work out as planned. The hypothesis has been refuted. The tap water had fifty-eight paper clips compared to the soapy water with sixty-two paper clips. The reason behind the cohesiveness increasing is because the method used for the first one was not the same method used for the second one.
Materials
Materials needed for the procedure include tap water, dawn dish detergent, paper clips, a plastic cup, an eyedropper, pencil and paper to record results.
Procedures
In the experiment with just tap water it included one hundred milliliters of tap water. Then fifty more milliliters of water. Water was added with an eyedropper until the surface appears to be rounded or about to pour over. Then, the paper clips are dropped in the water until the water spills over. In the second experiment with soapy water it uses one hundred milliliters of water. Then, forty-eight more milliliters of water. Water is also added with an eyedropper until the surface appears to be rounded. Add paper clips until it spills over. Then record the results.

My results of part B shows that a penny can hold 21 drops of water on the top. This relates to adhesion since the penny that is copper is attracted to a different substance which is water. When the drops hit the penny, the adhesive force of the water and the penny keeps the water from falling off the sides. It also shows high cohesion since the water molecules are attracted to each other. In a water molecule it has a hydrogen bond of oxygen and hydrogen since they are attracted to one another. It has a positive charge of two hydrogen atoms and oxygen a negatively charged atom which allows them to be attracted to each other since positive is attracted to negative. Since water has a positive end and a negative end, it is a polar molecule since polarity has one positively charged end and the other is negatively charged.…

The yellow pod experimented to discover what happens when you put gummy bears in different types of water for one day. The yellow pod put gummy bears in a beaker filled with salt water and another container filled with tap water. The data collected shows that the tap water made the gummy bear grow faster than salt water and the gummy bear weighed 2.7 grams more when soaked in tap water compared to salt water. The tap water bear also grew 10 centimeters in height more than the salt water gummy bear. Also, the tap water bear’s leg fell off during the experiment. The hypothesis predicted that both water would make the gummy bears shrink, but the salt would make it shrink more. Based on the data collected, no further experiments will be needed.…

Procedure: First, three cups were labeled as #1, #2, and #3. Next, each cup had one teaspoon of dish detergent and ⅔ cup of water added to them and swirled around to have everything mixed. Cup #2 then had half a teaspoon of table sugar added and cup #3 had half a teaspoon of table salt added to them. After that, a straw was dipped into each solution separately, and blown through in order to make bubbles. Data was recorded while blowing bubbles.…
