What is porousity?

Answer 1

Porosity is a measure of the void spaces or pores within a material, typically expressed as a percentage of the total volume. It indicates how much fluid a material can hold and is a key property in fields like geology, materials science, and engineering. High porosity often correlates with better permeability, allowing fluids to flow through the material more easily. This characteristic is crucial for applications such as water filtration, oil extraction, and soil science.
