Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.

If the dimensions of the ship are (250 m) long, (80 m) wide, and (80 m) high. Determine how far the bottom of the ship is below the sea level? (Consider the total mass of the ship with the oil is (10.2*108 kg), and the .sea density is (1024 kg/m³))
