1. What happened over time to the oil spill when you dropped it on the fresh water?
When we dropped the oil onto the fresh water it floated to one side of the pan and stayed there for about 30 seconds. The oil started out as a blob of yellow that was about .3 centimeter thick and 12 centimeters in diameter. After two minutes, the oil floated from one side of the pan so it was covering over half of the pan. The diameter of the oil was then 26 centimeters, and the oil was about .1 centimeter thick. After four minutes, the oil floated so it was a thin layer of oil covering the majority of the pan. The oil looked clearer and was barley a yellow color. After six minutes, the oil was 35 centimeters in diameter, and it spread very quickly, covering the whole pan. It was transparent with a slight yellow color. It was also 35 centimeters in diameter, and spread across the whole pan, but the oil …show more content…
One similarity between these molecules is that they both have hydrogen atoms. Also, both vegetable and basic petroleum oil and water all have more than one hydrogen atom. One final similarity is that vegetable oil and water both have an oxygen atom. Although there are many similarities between vegetable oil, basic petroleum oil, and water, there are also many differences. For example, a water molecule only has two hydrogen atoms, but molecules for vegetable oil and basic petroleum oil have a lot more than two. Also, the water molecule has oxygen in the molecule, while the vegetable oil has oxygen as an output from all of the carbon and hydrogen atoms. One final difference between vegetable oil, basic petroleum oil, and water is that the water molecule does not have any carbon atoms, but the vegetable oil and basic petroleum oil does. Overall, there are many similarities and differences between vegetable oil, basic petroleum oil, and
