# Will a piece of ice, floating on water in a beaker, rise or fall when I add oil on top of water? [duplicate]

There is a beaker of water with ice floating on top of it. If I add oil (lighter than water and ice) to it such that it forms a layer above water and ice is suspended between those layers. Does the ice rise or fall from its previous level?

specific gravity of ice = 2/3 specific gravity of oil = 1/2

• Please be more specific. Some oils have a density greater than that of water. What is the density or specific gravity of the oil? Also, "Does the ice rise or fall from its previous level?" ... its previous level in water, or its new level in oil compared to its previous level in water with no oil? Commented May 2, 2019 at 18:47
• @DavidWhite It says "lighter than water and ice". I think it's safe to assume that is referring to the relative density.

• I still need the specific gravity of the oil. That specific gravity could be more or less than that of ice. Commented May 2, 2019 at 18:51
• @DavidWhite Suppose specific gravity of oil is 0.5. Commented May 2, 2019 at 18:52
• @DavidWhite Again, I assume "lighter than water and ice" was more to due with density than it was the net mass.
