Ignoring the temperature extremes you would walk on Mercury, though with some difficulty. No planet has such weak gravity that you would float. The surface gravity is 38% that of Earth. Astronauts on the moon, whose gravity is about 16% that of Earth found it difficult to keep balance while walking and instead moved around by jumping.
You can physically walk on Mercury, but since it is so close to the sun and it lacks an atmosphere, on side would be burning and the other would be extremely cold. I don't think you can survive either of the extreme temperatures.
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.
No, mercury is denser than ethanol, so it will sink and not float.
it will float
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
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.
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.
sit is to walk
Oil is denser than cork, so the cork would float.
No, rocks are denser than mercury, so they would sink in mercury. Mercury is a very dense liquid at room temperature, so objects that are less dense than mercury will float on it.
Mercury I think From the physics point of view: any liquid that has a Density higher than Lead will allow Lead to float on it. This is why if you make Custard at just the right consistency using a specific type of flour with a specific flour to custard ratio and fill a swimming pool with the mix you could walk across it with out sinking. The reason I am not going to give specific instructions on how to do this is because if you get the custard mix right it acts a bit like quick sand if you stop moving. Once you stand still on it you start to sink and the custard mix will hold you in the swimming pool as you sink. It could be very dangerous. So no specific instruction on how that can be done, just that it is possible. That said That same mix of custard will also allow lead to float.
