Just click the green flag, watch and click as instructed :^) . Oh and also since it doesn't repeat the conclusion or hypothesis, I placed both of them in the notes and credits below!
So this is a thing for school :^) - I tried to make a pastel grid aesthetic background but I think I failed oops - I don't own the song!! The song is titled "façade" by the user aBstracT on audiotool. - -------Citations------- 1)https://wow.osu.edu/experiments/States%20of%20Matter/Evaporation - 2) http://chemistry.about.com/od/moleculecompoundfacts/f/What-Is-The-Boiling-Point-Of-Alcohol.htm - 3) http://www.indypl.org/kids/blog/?p=8941 (~._.)~ Hypothesis ~(._.~) If I apply water to Roseart ink, then its colors will spread far because unlike Sharpie markers, the ink is water-based, not alcohol-based. The difference is that alcohol-based ink evaporates faster, leaving it less time to spread. However, water-based ink doesn't evaporate as fast, therefore it has time to spread. wow.osu.edu states, "The attraction between isopropyl alcohol molecules is not as strong as that between water molecules. Therefore, isopropyl alcohol molecules evaporate faster than water molecules." This shows that since the alcohol molecules aren't as attracted to each other, they had less time to spread before turing from liquid into gas form. ----Conclusion---- In conclusion, the type of ink affects the distance the ink spreads because alcohol-based ink (the Sharpie) spreads less, while water-based ink (the brown marker) spreads more. According to the data, it is evident that the brown marker spread much more than the Sharpie. The Sharpie stayed more like a dot while the brown marker spread into different colors and pigments. This is due to multiple reasons. After further research, not only is "the attraction between isopropyl alcohol molecules is not as strong as that between water molecules" (therefore since they aren't as attracted to each other as water, it is easier for the molecules to spread apart and turn into gas form), but also according to chemistry.about.com , the boiling points of different types of alcohol range from 151 degrees Fahrenheit, to 173.1 degrees Fahrenheit, to 177 degrees Fahrenheit. Regardless of the type, all three boiling points are lower than the boiling point for water, 212 degrees Fahrenheit. Since alcohol has a lower boiling point than water, one could easily conclude that alcohol evaporates more easily than water. Not only that, but indypl.org states,"If something will NOT dissolve in water it is called hydrophobic. Permanent marker ink is hydrophobic. The permanent ink WILL dissolve in rubbing alcohol." This also contributes to the reasoning that Sharpie (a permanent marker) will not dissolve, since it is hydrophobic, and dissolves better in alcohol. Both of those reasons add up to the conclusion that alcohol-based ink is unable to spread as much in water as water-based ink can.
