You create a column of the liquids in a glass cylinder with the most dense material on the bottom layer and the least dense on the top. You do not allow the liquids to mix.
a First you drop a plastic bead that has a density of 0.32 g/cm° into the column. What do you expect to observe?
The bead will float on top of all the liquids.
The bead will pass through the top layer and float on the n-butyl alcohol layer.
The bead will pass through the top two layers and float on the toluene layer.
The bead will pass through the top three layers and float on the ethylene glycol layer.
The bead will sink all the way to the bottom.
Correct
Since the bead is less dense than any of the liquids in the column, the bead will float on top of all the liquids.
b Next you drop a different plastic bead that has a volume of…
