Oil density of water is lower.
Yes, the ship is floating in the water.
Your egg is floating in water because it is less dense than the water. This means that the egg is lighter than the water, causing it to float instead of sink.
When detergent is added to a floating object in water, it can break the surface tension of the water causing the object to sink. This happens because the detergent molecules disrupt the cohesive forces that keep the object floating by reducing the surface tension of the water.
A lifebuoy or life preserver is a floating device used to help people stay afloat in water in case of emergencies.
The buoyant force on an object floating in water is equal to the weight of the water displaced by the object. This force acts in the upward direction, opposing the force of gravity acting downward on the object. If the object is floating, it means that the buoyant force is equal to the weight of the object, providing balance.
It dosent, waters density is lower then cooking oil, resulting in cooking oil floating on water
The oil is floating on water, so it density is lower than that of water.
Oil is not soluble in water. That's why two layers form when you pour oil onto water - the top layer being oil (it is less dense than water)
The oil is not repelled. It is floating on the surface of the water as a thin film. Water has very high surface tension, but when soap or detergent is added to water that surface tension suddenly drops. The water surface now contracts like a punctured rubber sheet toward the remaining area of high surface tension, dragging the oil film floating on its surface with it.

pertol,water and motor oil
When a glass of water is poured into a jar of vegetable oil, the water will not mix with the oil due to their different densities and polarities. Water is denser than oil, so it will sink and form a separate layer at the bottom of the jar. This creates a distinct interface between the two liquids, with the oil floating above the water.
Baby oil is less dense than water, so it floats on the surface rather than mixing with the water. This is due to differences in molecular structure and density between the oil and water. Oil molecules are non-polar and do not form strong attractions with water molecules, causing them to stay separate.
salad oil is hydrophobic (repels water) due to its nonpolar nature, while water is polar. This causes them to separate due to the difference in polarity, with oil floating on top of water as two distinct layers.
Oil and water do not mix because they have different polarities. When oil and water are mixed, they separate into distinct layers due to their different densities. This separation is a physical change where the molecules of each substance retain their original properties.
Water and oil do not mix together when stirred because they are immiscible. This is due to their different polarities - water is polar while oil is nonpolar. Instead, they separate into distinct layers, with water sinking to the bottom and oil floating on top due to differences in density.
When you mix oil and water, the oil forms droplets known as emulsions. These droplets remain suspended in the water due to their differing densities and the lack of a strong attraction between oil and water molecules, which prevents the oil from floating to the top. Additionally, emulsifiers can help stabilize the mixture by surrounding the oil droplets and preventing them from coalescing.
