Why a block of gold is more dense than a block of iron of equal size?

since gold has way more protons and neutrons in it's nucleus in each atom.


Which has more dense a steel or foam?

Steel is more dense than foam. Steel is a metal with a higher mass per unit volume compared to foam, which is a lightweight, porous material.


Does aluminum block contain a greater buoyant force or the iron block?

The aluminum block will experience a greater buoyant force compared to the iron block because aluminum is less dense than iron, making it more buoyant in water. The buoyant force is equal to the weight of the water displaced by the object, so the lighter aluminum block displaces more water and experiences a stronger upward force.


Will a block float in water?

It depends on the density of the block. If the block is less dense than water, it will float. If it is more dense, it will sink.


Is iron more dense than plastic?

Yes. Iron is more dense than plastic because its particles are closer together.


Is iron heavier or lighter than aluninum?

Iron is more dense.


Why does iron block displaces more water than a copper block of the same weight?

Iron is denser than copper, so a block of iron will displace more water than a block of copper of the same weight because the iron block takes up less space for the same mass. This means that the iron block will sink deeper into the water, displacing more water.

Why does an iron block displaces more water than that of acopper block?

There's no reason to say that it always does that. It only does if it has more volumethan the copper block. If the copper block has more volume, then it displaces morewater than the iron block does.In fact, if you get a styrofoam block that's big enough, that can displace more waterthan your iron block OR your copper block. It just has to be big enough.


Is iron less dense than silver?

Silver is more dense because silver is around 10.5g/cc, an iron around 7g/cc. silver atomic number 47, where as iron is 26. This means the nucleus will be much heavier, but also take up more space.


Why does a small volume of iron weigh more than a large ball of cotton?

Because iron is much more dense.
