A novel material called upsalite is the world's most water-absorbent material. Made of nanostructured anhydrous magnesium carbonate, this material is capable of absorbing several hundred times its weight in water, even in low-humidity conditions. Other record-breaking w...
Common heat-absorbing materials include precious metals such as silver, copper and gold. Materials that conduct more heat are capable of absorbing heat before transferring it. The most conductive naturally occurring material is diamond, followed by other pure metals. Th...
Some common materials that absorb sound well and that can aid in noise reduction are carpeting, gypsum wall board, mineral fiber ceiling tiles and fiberglass ceiling tiles. Materials that contain a greater degree of mass tend to be the better sound absorbers, but this m...
Sand absorbs water because sand particles have pores in them that, when dry, are filled with air. When the sand particles are wet, the air in the spores is replaced with water.
Roots absorb water from the surrounding soil using the process of osmosis. Plant and tree roots have special structures, called root hair cells, that cover a large surface area and act as tiny sponges to absorb maximal amounts of water.
The amount of water a sponge can absorb depends on many factors. The material the sponge is made out of, the structure of the sponge and the size of the sponge all affect how much water the sponge can absorb.
The small intestine is the specific organ that extracts water and salt from food, says About.com. The digestive system as a whole contributes to nutrient absorption in the human body.
