Detailed explanation-1: -Water absorbency is a measure of the amount of water absorbed by the wetted surface of paper and board materials.

Detailed explanation-2: -Water absorption refers to the ability of material to absorb water when immersed in it and is represented with water absorbing capacity. In the equation: WW is mass water absorbing capacity (%); WV is volume water absorbing capacity (%); m2 is the mass of material saturated with water (g);

Detailed explanation-3: -It is calculated as the moisture content, which is equal to: (weight of the container with wet soil minus the weight of the container with dry soil) divided by (weight of the container with dry soil minus the weight of the container), then multiplied by 100 to express it as a percentage.

Detailed explanation-4: -Materials that can absorb liquids such as water are called porous materials. The word “porous” means capable of absorbing liquids. It comes from the word “pore” (small opening) because porous materials have small holes or openings that allow air or liquid to pass through.
