Lead is more dense than water.
Even though a sponge may be the same size as a book, the sponge has hundreds of holes in it. The book has far more material in the same amount of space that the sponge takes up. In other words, the book is far more dense than the sponge.
less dense
A pillow is less dense than a lead sinker. Density is defined by mass per unit volume. So, if you have the same mass (weight) of a pillow, and a lead sinker, which will take up more space (volume)? The answer is the pillow. Thus, it is LESS dense.
assuming they are the same size/shape, the steel ball would because it has more mass and is more dense.
A sponge has air bubbles.
Lead is more dense than water.
The soap is more dense than the sponge because it has greater mass.
yes, cotton ball will absorb more than sponge
Lead is more dense than air.
Lead
Yes that is right.

No, lead is more dense than aluminium.
A square inch of lead because lead is more dense
That depends on what is it made of, however even lead cannon ball would float in mercury, let alone steel one. If you compare densities, you can see that mercury is more dense than lead in room temperature (13530 kg m-3 vs 11 540 kg m-3). One can imagine a cannon ball made of depleted uranium perhaps, which would sink in mercury, being more dense.
