What is another word for porousness?
Pronunciation: [pˈɔːɹəsnəs] (IPA) 
Porousness is a term used to describe the ability of a material or substance to allow the passage of fluids, gas, and even solids through its pores. When describing this aspect of an object, there are several alternative words that can be used in place of porousness. These synonyms include permeability, absorbency, absorbance, infiltrability, penetrability, and porosity. Permeability refers to the ease with which fluids flow through an object. Absorbency and absorbance, on the other hand, describe an object's ability to soak up liquid or gas. Infiltrability and penetrability relate to the degree to which an object allows materials to pass through it. And then, porosity describes the extent to which an object is filled or surrounded by small holes or openings.
