what is an example of a permeable substance? how about an impermeable substance?

Question

i really need some answers please...

Answer 1

Permeable:
allowing fluids or gases to pass or diffuse through; "permeable membranes"; "rock that is permeable by water" [ant: impermeable]

Example: Concrete(allows water to pass slowly through)
Cloth
Sand
paper

Impermeable:
Glass
Plastic
Steel
Aluminum

An impermeable substance means that it has porosity, and that porosity is connected. This allows a liquid to flow through the material. So yes, soil and sand would be examples of permeable materials, as they allow water to filter through them. However, in a more geologic sense (and found underground at depth), what we would be looking at is the actual rocks. Rocks that have permeability include sedimentary rocks such as sandstones, conglomerates, and (to a slightly lesser degree) shales. This permeable characteristic of sandstone is actually one of the reasons why it is a great reservoir for petroleum (oil) deposits. Impermeable substances would include most igneous and metamorphic rocks (ex. granite, basalt, marble, schist, gneiss, etc...). These rocks don't usually have any porosity in them and therefore are unable to be permeable. Some extrusive igneous rocks (such as pumice or vesicular basalt) can show porosity due to gas escaping upon rapid cooling, however these pore spaces are rarely interconnected, therfore they are still not permeable rocks.

Answer 3

Permeability is the measure of how a particular material transmits fluids. It kinda depends on what context its being used though.

Here are some definitions:

2. Also called magnetic permeability. Electricity. a measure of the change in magnetic induction produced when a magnetic material replaces air, expressed as a coefficient or a set of coefficients that multiply the components of magnetic intensity to give the components of magnetic induction.
3. Geology. the capability of a porous rock or sediment to permit the flow of fluids through its pore spaces.
4. Aeronautics. the rate at which gas is lost through the envelope of an aerostat, usually expressed as the number of liters thus diffused in one day through a square meter.
5. Nautical. the capacity of a space in a vessel to absorb water, measured with reference to its temporary or permanent contents and expressed as a percentage of the total volume of the space.

Impermeable Substances include some types of rocks (with smaller pores), plastic materials and usu. vaccum coverings of some sort (I don't know the exact terminology) Semipermeable substances usu. include filter paper while permeable...well that's easy: anything that allows passage of water without absorbing anything (can't think of anything concrete right now, sorry)

Hope this helped :)

Answer 4

Say an oil tank in a tank farm is perched over just the standard soil this soil will allow the leak from the tank to soak into the soil and thus it is classed as A permeable substance . If the same tank was perched over a concrete base the leak would stay within the concrete bunding and can be sucked up into say a tank therefore that concrete bunding is made of a non permeable substance~~

Answer 5

What Is Permeable

Answer 6

impermeable: plastic bag.
permeable: strainer or paper towel

Answer 7

m nt sure but in upper course the water will flow wid d usual speed but whn it passes through the lower course the flow as in d speed will change cuz it has permeable rock

Answer 8

bruh

Answer 9

I am not sure....sorry.:(
