What percentage of water volume can porosity indicate?

Porosity is a crucial property of materials that indicates the volume of voids or spaces within a substance, such as soil or rock, compared to its total volume. This property is essential for understanding how much water can be stored in a medium, which directly influences groundwater supply, management, and resource planning.

The range of porosity is between 0% and 100%. A porosity of 0% means the material is completely solid with no voids, while a porosity of 100% indicates that the material is entirely composed of voids, with no solid material present. Thus, the percentage of water volume that can be indicated by porosity varies widely, encompassing the entire spectrum. This is why the option stating a range of 0% to 100% reflects the nature of porosity accurately, making it the correct choice.

Other options provide narrower ranges that do not adequately capture the full potential variability in porosity, thus not representing the universal principle of this property.
