Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
Because their density is greater than ' 1 '. That means that any amount of rock material is heavier than an equal volume of water. A rock will float in mercury, though.
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.
No, it sinks.
Mercury would not float on water. This is because the density of Mercury (5427kg/m3) is greater than the density of water (1000kg/m3).
Look at the density of each substance. Iron is less dense than mercury, so yes, it will float.
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.
Because their density is greater than ' 1 '. That means that any amount of rock material is heavier than an equal volume of water. A rock will float in mercury, though.
it will float
Strictly be density, nickel should float on mercury.
Solid iron will float in liquid mercury. In most liquids it will sink.
No, they are not bouyant. They won't float on water, but they will float on mercury.
Pumice rocks have been known to float across oceans.
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.
Which rock? Any liquid that is dense enough will support a rock; the most common would likely be mercury, in which even iron floats.
