Scream at a brick building, and if you don't hear any echo then yes it does
No they most definitely do not absorb sound
Cotton absorb sound because it has small area that sound penetrate and doesn't reflect .
You mean which one does it travel faster in? It would be a brick because of how tightly packed the molecules in the brick are together. Wood, which is a lot more fragile that brick, does not allow sound to travel through it as fast.
it absorbs sound well
Usually, stuff that is soft will absorb sound.answ2. Sound is a vibration of air molecules, and anything that may be made to absorb energy from the molecules will absorb sound. If the material has soft fibres, and can allow the sound to penetrate easily, (is porous) then the collision of sound molecules with the fibres, will transfer the energy from the molecules to the inelastic fibres, where it will be dissipated as heat.
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.
No, the word 'brick' does not have a long "you" sound. It is pronounced with a short "i" sound, as in "kick" or "stick."

No, concrete does not absorb sound as it very dense.

Does it absorb water? Does it have small holes in it? THINK!
