Yes (air bubbles).
This depends upon what you wish to absorb. Corn starch is a good absorber of sweat. As is Talcum powder. A pneumatic cylinder in which the fluid/gas is forced through a small orifice is a good absorber of energy (car 'shock absorbers'). A Matt black surface is a good absorber of light, and if chosen carefully, may also absorb microwaves or infrared/heat. Light weight porous materials may be good absorbers of sound energy. Sawdust is often used to absorb oil or water. At the roadside, the fire brigade will use sand to absorb flammable fluids. A sponge is great for water.
Rubber is a good sound absorber because of its ability to dampen vibrations and dissipate sound energy. It is often used in applications where noise reduction is important, such as in flooring, car tires, and industrial machinery.
One real life example of an absorber is a sponge soaking up water when cleaning spills on a kitchen counter. The sponge absorbs the liquid by drawing it into its porous material.
No, you can be both good and evil. This is the same concept. The object is either a good absorber or a good reflector, and can not be both. Black is a good absorber, white is a good reflector.
Well, honey, let me break it down for you. A good absorber of radiation is also a good emitter. It's like a give and take relationship - what goes in, must come out. So, if something sucks up radiation like a sponge, you can bet your bottom dollar it's gonna spit it back out just as well.

Polystyrene is neither sufficiently porous nor of sufficient mass to be either a good Sound Absorber, or a Sound Barrier. [Those are the proper technical terms.]
Yes it is a good absorber. There are many reasons why it is a good absorber. One of the reasons is because it is very porous.
Yes
clothes are the most absorber of sound
Some example is sponge.Because a sponge can absorb a water or a solvent absorber.

Lead is actually used as a sound absorber
it absorbs moisture which may be caused by heat it may also be a good absorber for dirt and dust
