Question

why some material do absorb water?​

Answer 1

Some materials absorb water due to osmosis.

In order to understand why some materials absorb water, we need to understand about osmosis

What is osmosis?

• Osmosis can be described as the movement of water particles from a higher concentration to a lower concentration along a concentration gradient.
• When the water content will be less in a material than the outside environment, the material will absorb water due to the phenomenon of osmosis.

Hence, osmosis is the reason that some materials absorb water.
