Comparing Liquids To Float On Water, Oil, And Methanol

1) The samples that would float on water are water (if in an ice form), oil, methanol, 2- propanol and lead because these materials are less dense than water, which leads to them laying on top, or until they dissolve. The samples that would sink in water include aluminum and copper because they are denser than water.
2) The order of the four liquids that I would layer them in a graduated cylinder from bottom to top consist of: water, oil, 2- propanol, and methanol.
3) Working with specific gravity would be different from working with density. These two topics are similar but differ. The specific gravity is the answer of density. It’s the ratio of the density of a given soli or liquid substance to the density of water. Also, density has units,
