Ice floating in a cup filled to the brim with water will not cause the water to overflow when the ice melts. This is because the mass of liquid water displaced by the ice must equal the mass of the ice including that part of the ice that floats above the surface of the liquid. Consider a different situation. An ice cube is placed in a cup, and the cup is filled to the brim with mineral oil, which has a density of 0.8 g/cm3. The density of ice is about 9% less than the density of liquid water, which is about 1 g/cm3. After the ice melts, what will happen to the level of the water/oil mixture in the cup
