🇬🇧🇪🇸 permeability - permeabilidad : English Lesson

Meaning of "permeability" ("permeabilidad"), detailed definition, and a short video lesson below.

Permeability is a science word that tells us how easily liquids or gases can move through something. If a material has high permeability, things like water or air can slip through it quickly, like water through a sponge. If it has low permeability, water and air have a hard time getting through, like trying to push water through a brick. Scientists use this word to describe how leaky or how solid a material is when it comes to letting water or air pass through.

Watch and listen to this English flashcard to understand the word in more detail, with an easy example sentence.
