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.
Mercury, although liquid, is denser than most solids - as a result, most solids will float on it. However, mercury may form alloys with many metals, and so your silver dollar may be damaged. It is also toxic.
mercury
Strictly be density, nickel should float on mercury.
No.Lead has a very high density and will not float in alcohol
It will sink in water, but it will float in mercury. Depends on what the liquid is.
Sink or float... on what? - The general rule is that an object will float if it has less density than the fluid (gas or liquid) in which it is placed.
The density of the object goes through the less denser liquids until it gets to a liquid that is more dense than it. The first liquid that is denser than the object, the object will float on the liquid. My class did this in Science Class.
Lead floats in mercury.
Yes the boat will float on liquid soap
If it is heaver than water (or what ever liquid you put it in) it will sink. Lead will sink. A cork will float.
It is quite common for various things to float in water. But any liquid can cause things to float.
You can't float but you can fly. (Floating implies liquid, and Pluto has no liquid that we know of).
The liquid which is less dense will float on top of the liquid which is more dense. Density affects the liquid's level.
it will float
Solid iron will float in liquid mercury. In most liquids it will sink.
An object will float if it has less density than the liquid in which it is placed.
An object will float in a liquid when the density of the liquid is higher than that of the object or when equal. That is to say Upthrust= or >weight of the object
With a density of 13.5 g/cm3, mercury is the only liquid (at least at room temperature) denser than lead which has a density of 11.3 g/cm3.
i think you mean how does an object float if you did here is the answer most solids float on liquid because it has air in it (sponge) or it is lighter than the liquid.
