If a material will not allow water to pass through it, the material is considered ________.

Explanation:
Understanding how materials handle water is about permeability. Permeable materials have pores that allow water to move through; porous simply means the material has pores, which typically enables flow. Impermeable materials block water entirely, acting as a barrier. In this scenario, since water cannot pass through, the best description is impermeable. Transmissive isn’t the standard term used to indicate a complete block to flow in this context.
