It may block some sound, but it is rather ineffective as a sound insulator.
It floats.
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.
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.
no, they absorb it or the sound waves bounce off.
Acoustic foam is AA kind of foam designed to block sound

No. Styrofoam, or polystyrene, does not decompose. Chickens will easily peck it into little bits and swallow it where it may block their intestines and kill them. Styrofoam is a dangerous product for birds and animals.
That depends on the substance from which it is fabricated. A concrete block is heavier than a styrofoam or tofu block with the same dimensions.
Styrofoam does absorb sound but it reflects it also. It absorbs more than a brick wall but not as much as softer foams. It does make very good heat insulation.
It depends (on the density what you are measuring). Block of Styrofoam would weigh less than a block of lead.
A block of pumice stone, an iceberg, a log of wood, and so on. Thanks to H Z below, I never even thought of styrofoam.
You could use a wooden block, a Styrofoam cone, a birthday party hat... anything like that.
It is used to "block" the opening in walls and slabs during concrete pouring. This is usually made of wood or styrofoam.
Yes, block has a short "o" sound. "Broke" has a long "o" sound.
ummm i think maybe using an opposing sound to block of the first, this has been done with things such as fans and such basically you block sound with sound
No you retard
