The cause is the difference in density; the density of water is 1 g/cm3 and for Mercury is 13,5 g/cm3.
Glass floats in mercury because mercury is much denser than glass, creating a buoyant force that allows the glass to float. In contrast, water is less dense than glass, causing the glass to sink due to its higher density. The buoyant force in water is not enough to support the heavier glass object.
If the marble sinks in water, it is more dense than water. Objects that are denser than water will sink, while objects with lower density will float.
You can try using a suction cup or a piece of duct tape to lift the marble out. Alternatively, you could fill the vase with water to help float the marble to the top for easier removal. Be careful not to damage the vase or yourself while attempting to remove the marble.
Anything that doesn't float in water is less dense than water, say iron? So if you drop an iron bar into a glass of water, you can say that the iron sinks or you can interpret it as the water floats? If you are referring to liquid, then mercury.
Mercury is a metal unlike water which have hydrogen bonding. Mercury does not wet most substances, because of its high cohesion and low adhesion to the glass mercury will not wet glass. Cohesion, along with adhesion(attraction between unlike molecules), can help explain mercury phenomena. Mercury has a surface energy over 6 times greater than that of water so there is a much greater attractive force between the atoms of mercury than between the molecules of water, so mercury does not wet glass.

If an object floats in water it will also float in the much denser mercury
no
Because the marble has a higher density than the water does
The marble will sink.
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
The force of gravity is what causes the marble to sink to the bottom of the glass of water. Gravity pulls the marble downward towards the center of the Earth, overcoming the buoyant force exerted by the water.
First it floats, then it melts and makes the water colder.
The force of gravity pulls the marble downward, causing it to sink to the bottom of the glass of water. The weight of the marble exceeds the buoyant force acting on it, which results in its downward motion through the water.
Put something in a glass of water, and see if it floats.
liquid water is more dense than solid water
If the marble sinks in water, it is more dense than water. Objects that are denser than water will sink, while objects with lower density will float.
