Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.
Rocks are generally denser than water, so they sink instead of floating. The buoyant force acting on an object in water is not sufficient to counterbalance the weight of most rocks, causing them to sink. Additionally, rocks are not porous enough to trap enough air to make them float.
Yes, polypropylene would float on mercury due to its lower density compared to mercury. Polypropylene has a density of around 0.9 g/cm³, while mercury has a density of about 13.6 g/cm³, making polypropylene less dense and causing it to float on mercury.
No, it sinks.
Which rock? Any liquid that is dense enough will support a rock; the most common would likely be mercury, in which even iron floats.

Pumice floats in water, but for other rocks you'd need to find a fluid that's more dense than the rocks to float them in. For example, mercury is almost 6 times as dense as granite, so a lump or slab of granite will ride right up there high in a pool of mercury.
The floating rocks of Avatar are not real. However, many rocks of various sizes are suspended in space, particularly in the asteroid belt of our solar system. And the rock pumice will float in water. Technically, many other rocks would float in liquid mercury.
Well rocks don't float because they are a solid with no air.
Yes, nickel can float on liquid mercury because the density of nickel is lower than that of mercury. This means that nickel will not sink when placed on liquid mercury, and instead will float on its surface.
it will float
No, mercury is denser than ethanol, so it will sink and not float.
Solid iron will float in liquid mercury. In most liquids it will sink.
Yes, wood will float on mercury because mercury is much denser than wood. The density of mercury is about 13.6 times greater than that of wood, so wood will not sink in mercury and will actually float on its surface.
No, they are not bouyant. They won't float on water, but they will float on mercury.
