permeability
If I am trying to build a soundproof room, I would use foam and egg cartons for materials.
A young river is very active. It is still at the upper course. It moves at a characteristic high speed that enhances its active down-cutting and under-cutting. Its competence is very high due to its speed. An old river on the other hand is characterised by its materials and also the topography of its course. The old river has lost its competence due to the gradient of its course. The speed is low compared to a young river.
A cell wall on both the plant & animal cells. a cell membrane (yes membrane is spelled M-E-M-B-R-A-N-E.) in just a plant cell. the following contribution is by Draycos a SEMIPERMEABLE membrane will allow some substances to pass and prevent other substances from passing. another name for this kind of membrane is SELECTIVELY PERMEABLE
It is theorized this is a byproduct of the accretion of materials near a black hole residing in the center of the quasar.

Porosity refers to the amount of pore space within a material, while permeability refers to the ability of fluids to flow through that material. Materials can have high porosity but low permeability if the pore spaces are not interconnected or are blocked, which would inhibit fluid flow. Conversely, materials with high permeability typically have interconnected pore spaces that allow fluids to flow easily.
Earth materials vary in their capacity to hold water due to differences in their porosity and permeability. Porosity refers to the amount of pore space within a material, while permeability describes how easily water can flow through it. Materials with high porosity and permeability, such as sand and gravel, can hold more water compared to materials with low porosity and permeability, such as clay and bedrock.

Permeability is the measure of a material's ability to allow water to move through it. It is often used to determine the rate at which water can flow through soils or other porous materials. High-permeability materials allow water to move quickly, while low-permeability materials impede water flow.
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
The relative permeability of Teflon is very close to 1, indicating that it is a poor conductor of magnetic fields. Teflon is generally considered to be non-magnetic and has low permeability compared to ferromagnetic materials.

The permeability value for hydrogen sulfide (H2S) can vary depending on the material it is passing through. Generally, H2S has low permeability in most materials due to its small molecular size and polar nature. Polymer materials with high permeability to gases like silicone rubber are more likely to allow the passage of H2S.
Permeability is a measure of how quickly water can move through porous soil or bedrock. It is determined by the size and connectivity of the pore spaces within the material, with greater permeability indicating faster water flow. Materials with high permeability, such as gravel or sandy soils, allow water to move more quickly compared to materials with low permeability, like clay or solid rock.
Permeability is a measure of how easily fluids can flow through a porous material such as soil or rock. It is a property that affects the movement of fluids like water and gases through the material. Materials with high permeability allow fluids to flow through them easily, while materials with low permeability restrict fluid flow.
