A glass cylinder contains four liquids in four separate layers. One liquid is
water. The purple liquid has a density 1.62 g/cm3. The yellow liquid has a density of 0.46
g/cm3. The red has a density of 0.91 g/cm3. What is the order of the liquids in
the cylinder? Explain your answer. What will happen if you slip a small, flat, chip of wood (density
0.85 g/cm3) into the cylinder?
