Question
Please explain by discussing how buoyant force of the oil would effect the bottle, and why exactly it does what it does when the oil is added.
Oil is less dense than water. A small, sealed bottle has a density halfway between the densities of oil and water. Therefore, the bottle floats if placed in water, but sinks if placed in oil. Say the bottle is initially floating in water, like this Bottle Water Now, oil is poured on top of the water. Does the bottle (a) Remain still (b) Move downwards (c) Move upwards. Explain.Explanation / Answer
When the oil is poured on top of the water the oil will float above the surface of water because oil is less dense than water. Water molecules are polar and they are strongly attracred to each other. When oil is poured on water, when the density of bottle is more than the density of oil the bottle remain still.
Consider the Specific gravity is fluids. Specific gravity of water is 1. Specific gravity of vegetable oil is less than 1. According to the question bottle sinks in oil. That means the density of bottle is more than the density of oil. As the bottle floats on water the overall density of bottle is less than water.
Hence the bottle remain still when oil is poured on top of water
