Question

how do you describe the materials that absorb water ?​

Answer 1

Answer:

Sponge and cotton is very porous, which makes it a natural absorber of water. Porous materials or materials that absorbed water have tiny holes or pores that allows water to pass through it. Why materials that repel water or non- porous materials does not allow water to pass through it.

Answer 2

The sponge-like material swells up with water because the gaps between the resistant components contain fibers that absorb the water.

Explanation:

• When one wets a sponge, it absorbs the water. This occurs because the sponge's bubble-like pockets have the potential to hold water, and the sponge substance seals it in.
• Water molecules like to cling to cellulose, which is found in the paper. As a result, paper absorbs water quickly.
• The OH groups on the cellulose molecules’ outside edge can be seen if one examines its structure. Negatively charged groups attract water molecules, allowing cellulose and cotton to absorb large amounts of water. Cotton can absorb water at a rate of 25 times its own weight.
