From top to bottom phases: hexane, HDPE, water, PVC, perfluorohexane, Teflon.

Work Step by Step

We need to compare the densities of these substances, and since none of them dissolves in another, each one of them will form their own phase. The phases with lower density will be above those with a bigger density. Densities in g/cm$^3$: Hexane- 0.766 HDPE - 0.97 Water - 1.0 PVC - 1.36 Perfluorohexane - 1.669 Teflon - 2.3
