No, lead is not buoyant. It is incredibly dense, which makes it very heavy, and not able to float.
That depends on the amounts, of course - what exactly you are comparing. The buoyant force depends on the volume. For a certain volume of lead, there will be the same buoyant force as for the same volume of iron. On the other hand, since lead has a greater density, the buoyant force on a certain amount of MASS of lead will be less, compared to iron, since the same mass of lead will use up less volume.
it can be more or less buoyant be having more or less mass.i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.
Yes
The block of Styrofoam floats on water while a same size block of lead lies submerged in the water. The buoyant force is greatest on the lead. Compared to an empty ship, the same ship loaded with Styrofoam will float lower in the water.
A balloon attached to a lead weight.
a small helium balloon :) i think.... i dont actually know the answer i just know that a small helium balloon will be very buoyant :)
I would say the the lead displaces less water. Think about the sizes and densities. If you have a block of lead and a block of aluminum (weighing the same), common sense tells you, the lead block is going to be a lot smaller due to his great density. Therefore, smaller block displaces less water
buoyant
Buoyant and light-hearted
Sodium chloride isn't buoyant.
Yes, there is a buoyant force acting on you when you are submerged in a fluid. However, whether you float or sink depends on the relationship between the buoyant force and your weight. If the buoyant force is greater than your weight, you will float; if it is less, you will sink.
Uranium is not buoyant; uranium is a very dense metal.
