Float.
No, water will sink in oil because oil is less dense than water. This causes the water to be heavier and sink below the oil.
No, it is not. Oil and water do not mix. If you pour oil into water, the oil will float to the surface. If you pour water into oil, the water will sink to the bottom and the oil will float on top.
Yes it will float until it is less denser than oil and water. But just after increasing its density by absorbing enough water or oil it will start sinking.
No. Oil will float on vinegar as vinegar has the same density as water.
Most (but not all) oil is less dense than water. That oil which is less dense than water will float. That oil which is denser than water will sink.
because of the salt in the water
It depends on the density of the materials and the type of oil. In general, materials that are less dense than oil will float on oil, while materials that are more dense than oil will sink. Oil has a lower density than water, so materials that float on water may or may not float on oil.
No. For their size, diamonds are heavy and will not float.
does water sink or float in what? whether one solution "floats" or "sinks" when added to a 2nd solution depends largely on the relative densities of the two solutions. Generally the denser of the two will "sink", though other factors, such as polarity, come into play in certain situations (eg, mixing oil and alcohol).
This depends on the type of oil. Few types of oil sink in water, while most types of oil float on top of the water.
it will float as long as it is not fully covered water.
Oil does not sink in water. Almost all oils and fats are less dense than water so they will float.
